GAS FOR ANALYZER TEST
To verify proper analyzer operation and to train users, Micromeritics representatives will analyze
the reference material provided in the analyzer accessories kit.
The following gases are required in order to analyze the reference materials. If these gases are
not available, Micromeritics representatives will only be able to perform a limited number of
analyzer tests during installation and operator training.
All gases require the indicated purity.
All analyzer types Chemical adsorption units
(CGA 580) N

99.999%
(CGA 580) He 99.999%
All gases listed to the left and:
(CGA 350) H

99.999%
(CGA 350) CO 99.990%
Pre-mix 10% CO in helium (required for Dynamic Chem-
ical Adsorption units and TCD units only)
Any additional gases that may be used after the installation is complete can be connected by the
Micromeritics representative.
DEGAS UNIT
Although some samples can be degassed on the analyzer, it is highly recommended that a
separate degas unit — such as a Smart VacPrep — is available to ensure that proper degassing
of all sample types can be performed. Using a degas unit avoids moisture and contamination in
the analyzer.
