Gas Management
The Carrier Gas Purification illustration
shows the most common gas purification
configurations used in gas chromatography.
Regardless of which purification
system is employed, proper installation
and maintenance is required to
achieve optimal performance from
the purification system(s). A purifier
that is not maintained will eventually
expire and become ineffective, or worse,
a source of contamination.
• Determine desired purity level.
• Keep number of fittings in gas line
to a minimum.
• Install purifiers in a convenient location
close to the GC.
• Purifier log books are useful for
determining maintenance schedule.
• Use indicating traps closest to the GC
so you can determine when to change
the traps that are upstream.
