| Everything
you need for TO-14 type analyses except
for compressed gases and a PC ! |
For
TO-14 analysis and ambient air analyses of all
types, this GC configuration has everything you
need in a compact, easy to transport package.
Small enough to take on-site for real time measurements, you can avoid the need for
expensive, labor intensive canister sampling by
performing the analysis right at the source.
By comparing the
relative response, the three detectors make peak
identification and confirmation easy. The FID
responds to all hydrocarbons, the PID to selected
hydrocarbons, and the DELCD to halogens only. The
dual-trap sample concentrator is similar to the
SRI purge & trap but has a gas inlet instead
of a liquid purge vessel ( the liquid purge head
can be added if required ). The innovative
dual-trap design results in more efficient
trapping and desorb than single trap designs,
especially for the early eluting peaks such as
vinyl chloride.
The built-in
"whisper quiet" air compressor
eliminates the hassle of transporting bulky air
cylinders by providing an endless supply of
combustion air for the FID/DELCD detector. The
user need only transport small cylinders of
carrier and hydrogen (or get the Stand-Alone
SRI Hydrogen Generator for both the FID fuel and carrier
gas!) which are used at a much
lower rate than air, thus a small cylinder will
last for weeks or months of operation. The vacuum
pump interface allows the PeakSimple data system
to turn a vacuum pump ( not supplied ) on and off
under control of the software. The vacuum pump is
used to draw ambient air through the traps for a
precise amount of time thus enabling the system
to sample unattended, The 60-meter capillary
column is the newest unbreakable fused silica
lined stainless steel technology, and gives good
separation of the TO-14 analytes with short run
times.
The PeakSimple
data system controls and sequences the entire
analysis, collecting data from the three
detectors, loading and desorbing the traps, then
printing and calculating the results. Because all
the A/D hardware is inside the GC chassis and
communicates to your notebook or desktop PC
through a standard serial port cable, no boards
need to be installed in your computer.
