Gas Requirements
Use the following guidelines to ensure you have the proper gas supplies and
environment ready in advance of installation.
CAUTION—Hazardous Fumes
The exhaust gas of the instrument may contain hazardous fumes that pose
health and safety risks. Avoid an accumulation of gas. The exhaust gas must
always be removed by proper ventilation. Make sure that the installation site is
well ventilated. Do not vent directly into the laboratory.
♦
Operate the instrument near the gas supply and ventilation sources.
3.6.1
Nitrogen Gas Supply
NOTICE—Gas Specifications
The requirements and specifications for the gas supplied to the instrument have
major impact on the instrument performance. Observe the following notes:
•
If the gas supply pressure is varying or dropping below the specified
pressure range, it can impair the performance of the instrument.
•
Non-volatile hydrocarbons, such as compressor oils, in the gas supplied to
the system can cause permanent damage to the instrument.
•
If the supply gas is contaminated with particles (size ≥
0.1 µm), water vapor
or other non-volatile substances, it can impair the performance or even
damage the instrument.
•
Observe all requirements and specifications for the supply gas in this
manual to avoid damage to the detector.
Make sure that the location fulfils the following requirements:
♦
Make sure that the gas supply is regulated to a stable gas pressure
that is within the specified gas pressure range. (95-110 psig or 655-
760 kPa)).
