Gas Specific Purifiers and
Contaminant Traps
• Reduce gas impurities from high PPM
to low PPB levels
• Decrease baseline noise and increase
GC/MS sensitivity
• Replace three traps with one purifier
Description
VICI Melronics
Several types of contaminants are detrimental to GC
performance - notablymoisbJre, hydrocarbons, andoxygen.
VICI Metronics gas-specilic purifier modules are designed
to be placed in-line with the GC carrier or detector gas
supply to remove these contaminants from the analytical
gases
prior to entering the GC. The modules dramatically
reduce contaminant levels andabsorb a greater variety
of
contaminants than other products.
Performance is optimized by a multiple bed format. Each
bed
functions
at
a lowercontaminant concentration, resuhing
in a series
of
contaminant concentration gradients across
the length
of
the module. Advanced materials and design
features guarantee that the modules will produce gases
that are at least a factor
of
ten higher than a 99.9999%
"chromatography grade" cylinder
of
gas when the purifier
is supplied by a 99.995% cylinder. The cost difference
between the
two
grades
of
gas will
pay
for the cost
of
the
purifier several times over during its operating life.
