The
Gas-less™ Educational GC Models are ideal for undergraduate chemistry classes
where the principles of chromatography are demonstrated on the same equipment
the students will encounter in industry. All Gas-less Models include
a built-in "whisper quiet air compressor" and a CCD detector which detects
combustible (hydrocarbon) molecules only, but which can operate on air
carrier gas from the internal air compressor. This configuration
is ideal for teaching situations where compressed gas cylinders can not
be used due to safety restrictions or budgetary limitations. Because
the Gas-less GCs operate on their own infinite supply of room air, GC demonstrations
can be performed in the classroom instead of the lab. Unlike GC's which
require helium carrier gas, with the ongoing cost of cylinder rental, storage,
and gas consumption, operation of the Gas-less GC models is essentially
free except for the minimal cost of electricity. All SRI Gas-less
GC's are equipped with the built-in Model 203 PeakSimple data system which
provides powerful yet easy data acquisition and temperature programming
for the column oven. Two Gas-less Educational Models are available. Both
are identical except that the less expensive version does not include the
fast cool-down fans and circuitry. On this model, the column oven
will cool-down slowly unless the oven lid is manually raised. The more
expensive model with the fast cool-down fans will cool automatically at
the end of the analysis from 250ºC to 50ºC in less than 5 minutes.
0310-1005 Gas-less Educational GC with
manual cool-down $4295.00
0310-1006 Gas-less Educational GC
with fast cool-down $4995.00
