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.
