WARNING: dangerous gases! The chromatograph operates with various gases which may be more or less dangerous. Before carrying out work on the chromatograph, always determine which gases the chromatograph is operating with, in particular the composition of the sample gas. Pass all exhaust gases from the chromatograph into a common line and route away from the installation location. Always make sure that there is sufficient ventilation n n
n
if you are working with hydrogen since this forms an explosive mixture with air if you are working with liquid CO2 . Breathing in of larger quantities of CO2 results in an oxygen deficiency even up to unconsciousness or death through suffocation. if you permit the sample gas line to run empty, and the sample gas contains corrosive or toxic components.
The analysis of mixtures containing CS2 is not permitted.
WARNING: danger of explosion! The chromatograph may require gases for operation which form an explosive mixture with air! Before carrying out work on the chromatograph, always determine which gases the chromatograph is operating with. Pass all exhaust gases from the chromatograph into a common line and route away from the installation location. Always make sure that there is sufficient ventilation.
WARNING: danger of explosion! The chromatograph is intended for the analysis of gaseous flammable and non-flammable media. Hydrogen or inert gases are used as carrier gases. In the analysis of flammable media or when using hydrogen as the carrier gas, only traces of oxygen occur in the sample; in other cases, the oxygen content of the sample is limited to the concentration that normally occurs in inhaled air. The analysis of mixtures of flammable gases and other gases at a pressure of > 1.1 bar is not permissible for explosive mixtures. Flammable gases that are explosive under the conditions relevant to the analysis, even with the exclusion of oxygen, may only be contained in the mixture for analysis in concentrations that are not critical for safety.
CAUTION: danger of corrosion! The housing is extremely resistant to solvents, weak alkalis and acids. When used in envi ronments with strong alkalis and acids at increased temperatures, the resistance should be tested in individual cases.

Explosion protection The installation and operation of electrical equipment in potentially explosive atmospheres is re gulated by the guideline RL 99/92/EU (ATEX 137). Reference is made in this guideline to general technical regulations.
WARNING: The test certificate for your explosion-proof chromatograph only applies to the original configuration with connection and installation according to the Siemens circuit and piping diagrams. The explosion protection for your device is cancelled if one or more components are modified.
Conditions The test certificate together with any supplements includes all conditions specified for installation and operation of the chromatograph.
Identification for explosion protection The chromatograph is flameproof, i.e. the housing is resistant to an internal explosion pressure. The housing of your MicroSAM has a rating plate on which the identification for explosion protection is specified: II 2 G EEx d IIC T4
Switching on the chromatograph The power supply to the chromatograph must only be switched on if it has been correctly connected!
Opening the housing with the power supply switched off Before opening the housing in the potentially ex plosive atmosphere, the power supply must be switched off and an essential waiting time of 60 minutes subsequently observed.
WARNING: As a result of hot components and residual electric charges in the chromatograph, explo sions may occur if the housing is opened too soon. A corresponding reference to this is present on the chromatograph!
Opening the housing with the power supply switched on A diagnostics plug is located behind the status display panel. The housing must be opened in order to access this. In the potentially explosive atmosphere, this is only permissible with a fire permission certificate.
WARNING: Opening the housing in the potentially explosive atmosphere with the power supply switched on is only permissible with a fire permission certificate.

Cable type We recommend twisted pair cables, 0.14 mm2 , shielded, AWG 26. Conversion of serial interface to RS232 or RS485 MicroSAM has only one serial in terface which can be switched between RS232 and RS485. It is necessary to assign com1 to RS232 and com2 to RS485 in the System Manager, as described in the System Manager instructions. Terminating resistors for MODBUS with RS485 RS485 cables must be terminated at both ends with 120-Ω resistors in order to prevent reflections. This resistor is present in the MicroSAM. It can be switched on using the software. This is usu ally carried out in the MicroSAM which is furthest away.
CAUTION: explosion protection All conductors must be connected in the junction box. This means that cables must not have more conductors than are actually required. Always refer to the connection diagram.

Operation MicroSAM can be operated via Ethernet and a PC, or via the built-in control panel (MMI) of a MAXUM chromatograph, or via a network access unit (NAU).
Various stages of operation Operation on the PC comprises three stages: n n n
System Manager - network monitoring and configuration of the chromatograph EZChrom - development of method and control of analysis MMI emulation - operation and monitoring
System Manager → configure database and applications Provides the connection to the chromatograph, and an overview of the network. Serves for configuration and high-level monitoring of the chromatograph. Also branches to the MMI emulation, EZChrom and the basic editor. The System Manager outputs almost exclusively static displays, i.e. it fetches a table from the chromatograph's database, and saves it again later. Only results and alarms are displayed in dynamic mode. The System Manager displays the hardware in tables, i.e. the system table includes all hardware components of the chromatograph: detectors, valves, ovens, digital outputs etc. EZChrom → generate methods and sample sequences Methods and sample sequence lists of an application can be generated and modified using EZChrom, e.g. optimize evaluation parameters, modify time programs, display chromatograms and results, re-inte gration. Access to the chromatograph's database is exclusively static. MMI emulation → operation and monitoring This is identical to operation on the built-in control panel of a MAXUM or an NAU. It is used for operation and monitoring, e.g. view results, switch valves, modify temperatures. Ho wever, there are only minimum facilities for editing configurations and tables. MMI is always a dynamic display.
Where and how the data are organized One must be acquainted with the following terms when using the chromatograph: database, application, methods, sample sequences. The database All parameters of a chromatograph are saved in a database. This contains configuration data and applications of the System Manager, EZ Chrom methods, sample sequences, ar chive and alarm log. This da tabase can be viewed in static or dynamic mode. Static corresponds to a snapshot of the database, i.e. tables are imported from the database into the PC, edited, and subsequently exported to the chromatograph again. The display is not automatically updated. The data must be imported again in order to view modifications. Dynamic means that the values are updated as soon as they change. Most of the MMI displays are dynamic. With the System Manager, only the results and alarms. EZChrom is always static. In the System Manager, copies of the database can be saved on the hard disk, and saved da tabases loaded into the chromatograph (file extension.AMD). Application Applications share the chromatograph hardware. Parts of the system table are assigned to each application. These quasi ge nerate a virtual chromatograph. Each application has sample flows, one or more sample sequence lists, inputs/outputs, several EZChrom methods, basic programs, chromatograms, temperature controllers, pressure regulators, results.
26
SAM-Manual_E.vp, Issue 06.05.2004
Ope ra ti on Each chromatograph can have several applications. Methods A method contains information required to analyze a sample stream: configuration data of detectors, valves etc., peak detection parameters and evaluation parameters, time programs. Methods are generated using EZChrom and exported to the chromatograph's da tabase. Sample sequences These are lists of sample streams and assigned methods. Each application has at least one normal sequence and one calibration sequence. Although an application can have several sequences, only one is active at a time.
How the data originate n
n
n
n
When the chromatograph is switched on for the first time, it automatically generates the required entries in the system table by Plug&Play. However, the chromatograph only recognizes, for example, that it has an electronic temperature controller, but does not know which type of oven is to be con trolled using it. In the second step, all hardware of your chromatograph is completely written in the factory by a configuration program. The existing hardware is then assigned to one or more applications. The configuration program generates a text file which is imported into the chromatograph by the System Manager. The applicable data are subsequently determined, and entered using EZChrom: valve switching, evaluation parameters etc. These data are saved as methods and a sample sequence list using EZChrom. All data are finally exported together from the chromatograph's database as an AMD file using the System Manager, saved with the remaining documentation on a CD, and supplied with the chromatograph.
Monitoring the chromatograph's function MicroSAM is completely parameterized when you switch it on (if you didn't order a basic unit and an analytical module separately). It need only be integrated into the communication network, and calibrated of course. It is subsequently only necessary to monitor correct functioning at regular intervals. The LEDs The LEDs behind the inspection window of your MicroSAM provide a initial impression of the status of your MicroSAM. They have the following meanings:

Communication is taking pla ce
Establishment of communication The IP address is factory-set in the MicroSAM to 192.168.144.0xx. "xx" corresponds to the last two digits of the serial number on the rating plate. For example, the IP address is 192.168.144.047 if the serial number of the MicroSAM is HX R5 347. The Subnet mask is always 255.255.255.0. To permit your PC to communicate with the MicroSAM, its IP address must be in the same "world". This means that its IP address must be manually set to 192.168.144.0 to 255, but of course must not be identical to the IP address of the MicroSAM. We recommend that you set 192.168.144.254, and 255.255.255.0 as the Subnet mask. Once the System Ma nager has started, the new chromatograph must be entered using the function Add Unit. More detailed information on the subject of Ethernet networking can be found in the description of the System Manager. Alarms Open the associated chromatograph in the System Manager, and click on Alarm Log. All alarms are dis played here. These alarms can be deleted so that it is possible to check whether they occur again. Checking the chromatogram EZChrom can be used to compare the current chromatogram with previous chromatograms. This per mits conclusions to be made concerning changes in the analytical system. Checking the results EZChrom can be used to check whether the results are complete and realistic.
IMPORTANT The number of time events in EZChrom for MicroSAM must not exceed eight at the same execution time (Retention windows, valve switching etc.). Otherwise you will get an error message later while executing the time events. If you need more than eight time events at the same execution time, you must use slightly different execution times for groups of eight time events each.

Maintenance of the analysis module We use standardized analysis modules with MicroSAM. They are very powerful and thus are suitable for many different applications. The most important feature is the in-line detection. The columns and the thermal conductivity detectors (TCD) are connected in series. So MicroSAM can collect the results from the locations, where the component separation is optimum. The TCDs are semi bridges w/o reference. Two TCDs are connencted in each case to a complete bridge circuit in a way, that no overlapping of signals will occur.

Removing the analysis module WARNING Observe the regulations for explosion protection if the MicroSAM is installed in a potentially explosive atmosphere. When using the chromatograph in explosion hazardeous areas, a waiting time of 60 min. must be observed before opening the housing. Af ter this time, the surface temperatures inside the chromatograph have cooled to < 135°C and the electrical charge of internal components will have reduced to an uncritical level.

Adjusting mechanical zero of the pressure regulators If the pressure regulation is under suspicion to cause faulty analytical results, e.g. shifted retention times, the function of the pressure regulators should be checked, and the mechanical zero should be adjusted if necessary
WARNING This service procedure may only be carried out by trained experts. Danger of causing short circuits at the electronical boards. For adjusting the mechanical zero the appropriate special tool has to be used. On MMI in Maintenance Mode select the menu App I/O, Temperature & Pressure and in this menu the item Pressure Controller. In the column PWM you see the controller output signals for the four pressure regulators. The controller output should read 10 to 30 %. If this value reads 0 or 100 %, the mechanical zero should be adjusted. Using the MMI, adjust the set value for the pressure according to the application documentation. Then use the special tool to adjust the pressure regulator until the PWM value reads approximately 20 %.
The photo shows the position of the pressure reg ulators. On the lower left you will find reg ulator 1 (yel low arrow), the numbers increase counterclockwise. While adjusting, off course, the electronic boards are in place. You have to find the pressure regulators by "feeling" with the special tool.

The Live co lumn switching
The Live column switching Two columns are connected in series by the Live T-piece. The columns have e.g. different separating cha racteristic. The various operating sta tes of the live switching circuit are activated by pressure changes in the gas supply lines of the Live T-piece: Straight, Backflush, Cut. The electronic pressure regulators are controlled by time events. Straight The components pass through two columns in succession.
Backflush Once a number of components have passed through the first column, the flow direction in this column is reversed. The components which are still present in the first column are collected again at the beginning of this column and flushed out into the open air via the backflush outlet. This permits the analysis cycle to be drastically shortened: higher boiling components which only pass through the first column slowly need not be removed at a higher temperature, a process which often requires a long time. Cut Once a number of components have passed through the first column, they are flushed out through the cut outlet. They never reach the sec ond column. This method is used: n
n n
n
to keep components away from the second column which cannot be backflushed because they are followed by components which are still of interest if components falsify the result or damage the second column to directly pass components onto a further detector, e.g. in order to shorten the duration of the analysis to divide components further on a third column (distribution).
Advantages of live switching n n n n
40
The sample only comes into contact with metal parts in the live T-piece, but with no valves. There are no temperature limitations because the switching valves are mounted outside the oven. Maintenance-free since there are no moving parts. Minimum dead volume, highly suitable for capillary columns.

The Live co lumn switching
How Live switching functions Pressures and flows are important P1
P2
Atm.
Two columns are connected in series, and a pres sure of P1 is connected to the beginning. Atmospheric pressure is present at the end. The pres sure distribution and flows are then as shown on the left. Conclusion: In the straight operating mode shown here, the pressure P2 is present in the middle between the two columns. NOTE: In reality, the pressure drops are not linear, they are curved.
Time for reflection P1
P2
The pressure P2 read on the Y-axis in the above figure is now applied between the two columns. The input of the first column is left open. This re sults in a pressure distribution and flows as shown on the left. Conclusion: Backflushing is now being carried out in the first column.
Atm.
What we don't know yet ... If we wish to prevent a specific peak from disappearing into the second column once it has passed through the first column, we need an outlet betwwen the columns (cut outlet). And we need a con nection for he pressure P2 from the reflection above. The solution is the live T-piece. The two columns are connected via the coupling capillary in the Live T-piece (red in the right image below). Because this coupling capillary has a flow resistance, we have to recognize two pres sures now: P2 after the coupling capillary and P3 before the coupling capillary. In the Straight mode everything re mains like mentioned above at Pressures and flows are important. Just P3 has been added.

P2 P3
And now the cut We set P3 a bit lower than P2. The result is shown on the left. The components are flushed into open air as soon as they leave the first column. Because the pressure on the left hand side of the coupling capillary is lower than the pressure at the right hand side, all the gas from the first column is forced to leave via the cut outlet!
Atm.
If it really were that simple ... ... then we would be finished. Why does live switching therefore have to the adjusted? This we have done for you already in the factory. But it may be helpful for you, to understand the procedure anyhow: The live T-piece has 6 connections, of which the three right ones can be outputs. This means that a peak can be divided simultaneously amongst up to three outputs. And we can do without that! So we will inject a test mixture and monitor the detector signals at the three outlets. Then we have to decide, how to change the pressures P2 and P3, to get clear flow conditions for Straight and Cut:
Straight
P2
P3

Everything from the first column must enter the coupling capillary, and everything from the coupling capillary must enter the second column. This functions reliably if the "red" flow is supplemented by the flows of the auxiliary inlets P2 and P3. The flow direction in the coupling capillary is from left to right.

Everything from the first column must pass on to the cut outlet. This functions reliably if the "red" flow is supplemented by a sufficient flow of the auxiliary inlet P2. P2 also supplies the second col umn. The flow direction in the coupling capillary is now inverted from right to left. The flow P3 decreases automatically.
Backflush Backflushing functions exactly as described previously under Time for reflection. The position in which the live T-piece is currently being operated is irrelevant.
