Contaminant traps
For nitrogen for LCjMS
VICI Metronics nitrogen purifiers are
optimized for the high flow nitrogen
gas supply used on LCjMS
instruments. A nitrogen purifier
module placed in line with the
nitrogen gas delivery system
removes moisture, hydrocarbons,
halocarbons, and oxygen, retaining
them for the operating life of the
purifier.
Product information
For chemical ionization MS
In response to the increase in
commercial availability of
instrumentation for Chemical
Ionization Mass Spectroscopy, VICI
Metronics has developed a purifier
designed specifically for the unique
demands of the field.
Product information
Heated helium and nitrogen
pu rifiers
The purification substrate in VICI
Valco gas purifiers is a non–
evaporable heat-activated gettering
alloy. This stable alloy is contained in
a welded assembly, so the purifiers
can be used safely in industrial
applications with minimal
precautions. The miniature version
of each purifier is designed to be
installed in a GC's flow path
immediately upstream of the
injector.
Helium purifiers
Nitrogen purifiers
For nitrogen generators
The purifier for nitrogen generators
reduces most contaminant levels
from many parts per million to levels
that are below the lower limit of
analytical detection, and absorbs a
larger number and a greater variety
of contaminants than other
commonly used adsorptive materials.
Product information
For liquid carbon dioxide
VICI Metronics has developed a CO
2
purification technology which can
take Coleman grade CO
2
and
produce SFCjSFE grade CO
2
at the
point of use, resulting in significant
cost savings.
