INTRODUCTION
SOFTWARE
The Micromeritics-Cirrus Interface Software is used with select Micromeritics analyzers integrated
with an MKS Cirrus Mass Spectrometer. This software runs within the MKS Process Eye
Professional application. The Micromeritics-Cirrus Interface Software will perform the following
tasks:
lAutomatically collect data with the Cirrus Mass Spectrometer via trigger signal from the Micro-
meritics analyzer
lCustomize Peak Jump recipes
lAccess standard operations such as Analog scan, Barchart scan, Peak Jump scan, Leak Check,
and data storage
lCalibrate detectors
lScale the Micromeritics analyzer sample thermocouple signal
Refer to the Micro-Cirrus Interface User Guide (part number 292-42804-00) for details on operating
the interface software.
HARDWARE
The Mass Spectrometer requires periodic maintenance. Allow adequate space for accessing
connections and cables, as well as for ventilation. Refer to the Cirrus 2 Hardware Manual for
information pertinent to the Mass Spectrometer.

Hardware Installation
HARDWARE INSTALLATION
AUTOCHEM 2920 (SERIAL NUMBERS 700 AND BELOW)
REQUIRED TOOLS
lPhillips head screwdriver
l1/4 in. open-end wrench
l3/8 in. open-end wrench
l5/16 in. open-end wrench
l7/16 in. open-end wrench
l9/16 in. open-end wrench
The Mass Spectrometer connector is located on the side panel of the analyzer.
The TCD and cold trap valve zones of the AutoChem must be cool to allow safe hand-
ling of components. If necessary, allow a few hours for the zones to cool down after set-
ting the zones to 20 °C. Removing the cover and insulation at the zones will speed the
cooling process. The following illustration shows the original plumbing of the TCD/Cold
Trap zone.

1. Remove the rear panel and the entire top panel of the analyzer to allow full access to the
plumbing.
2. Remove the aluminum metal plate which covers the tubes inside the grooved bar inside the
heated zone. NOTE:This aluminum plate will not be re-used.
3. Loosen the screws which retain the plastic hose clamps, remove the side panel cover plate,
then remove the hard plastic center cap. Save the screws for later.
4. Remove the 1/8 in. tube from the sample exhaust side of the TCD. Disconnect the other end
at the hexagonal fitting, which is above the side panel exhaust ports.

Hardware Installation
5. Remove the two tubes that enter the ends of the TEE block. Remove the plug from the side of
the TEE block.
6. Remove the screws that hold the TEE block to the heated plate. An Allen wrench is provided
in the parts and accessories kit. Remove the two screws which hold the cover plate to a
grooved channel. Remove the cover plate.
7. Remove the screw from the grooved channel.

8. The tube that connected to the TEE (at the port that was closest to the front of the instrument)
must be connected to the rotary valve at the unoccupied port. This tube is shown on the left
side of the following illustration.
The 1/16 in. tubes are longer than required. DO NOT CUT THE TUBES. The tubing
has been cut, deburred and cleaned. Further cutting will introduce small particles which
can cause problems. If the tube is too long, either coil or zig-zag the tube to use the
excess length.
9. Before attaching the TEE block to the heated path, install one of the two 10.5 in. long tubes
(part number 004-03388-11, Hastelloy-C tubing 1/16 in. diameter × 10.5 in. long) from the cen-
ter of the TEE to the exhaust port of the sample side of the TCD.
Note the orientation of the TEE. It will be installed “upside down” so that the counterbore
for the original screw head is facing down.

Hardware Installation
10. Using a 1/8 in. to 1/16 in. reducer fitting, connect the other end of this tube to the exhaust of the
TCD.
11. Install the 31 in. long tube (part number 004-03388-16, Hastelloy-C tubing 1/16 in. diameter ×
31 in. long) from the right side of the TEE to the hexagonal fitting located above the exhaust
ports where the 1/8 in. tube was removed.
A 1/8 in. to 1/16 in. reducer fitting is required.
12. Using the new screw (part number 004-28310-01, 6-32 × 1.5 Pan Head Phillips), attach the
TEE as shown in the previous illustration.
13. Attach the new reducing union to the end of the Mass Spectrometer heated hose fitting. Use
the ferrules included with the reducing fitting.
14. Pass the Mass Spectrometer hose through the side panel cover plate. The black plastic
clamps above and below the Mass Spectrometer hose can be adjusted to prevent the Mass
Spectrometer hose from being pulled out of the heated zone. The insulation rings may be
used to prevent damage to the Mass Spectrometer hose insulation.
15. Re-attach the side panel cover plate, with the Mass Spectrometer hose passing through into
the heated zone.

16. Install the other 10.5 in. long tube (part number 004-03388-11, Hastelloy-C tubing 1/16 in. dia-
meter × 10.5 in. long) from the end of the Mass Spectrometer heated hose assembly (at the
1/16 in. end of the reducing fitting) to the left side port of the TEE. Nuts and ferrules are
included in the kit. The tube must be bent so that the metal connectors of the Mass Spec-
trometer hose are inside the heated zone.
The plumbing should now resemble these photos:

Hardware Installation
17. Replace the yellow foam insulation and the metal box covering the zone. The insulation may
be cut to fit around the Mass Spectrometer hose.
18. Reset the heat zones to the preferred temperatures. Set the Cold Trap Valve heat zone to the
proper temperature to ensure that the connection between the Mass Spectrometer end fitting
is heated, even though it is not directly clamped to the heated plates.
See Connect Cables on page 20 for instructions on connecting the cables from the
Mass Spectrometer to the analyzer.

The Mass Spectrometer connector is located on the side panel of the analyzer.
1. Remove the top cover panel and the upper rear panel of the analyzer.
2. Locate the Mass Spectrometer connection TEE block. It is mounted to a bracket behind a
cover plate on the upper rear of the left side panel. There are two types of bracket, depending
upon the serial number of the analyzer.
3. For serial numbers below 200, remove the two nuts which hold the Mass Spectrometer
bracket to the side panel. Save the nuts for later.
