and PTV injectors are upgrades to
the standard On-Column injector. There are
from which to choose. Up to five injectors may be
mounted simultaneously on Models 8610C and 8610D. The Model 310 will accommodate a single On-Column, Heated
Flash Vaporization, Heated Split/Splitless, or PTV injector. Rack-mountable Model 410 can accommodate a gas
sampling valve and a single On-Column, Heated Flash Vaporization, Heated Split/Splitless, or PTV injector.
Sample Types and Appropriate Injectors
LIQUIDS:
On-column, heated flash vaporization, heated split/splitless, PTV,
heated static headspace, purge & trap, liquid injection valve, or liquid
autosampler
SOLIDS:
Thermal desorber, heated static headspace, PTV, or Method 5035
purge & trap
GASES:
On-column, gas sampling valve, Method TO-14 air concentrator, or
heated static headspace
SPME FIBERS:
Heated flash vaporization with low volume SPME liner, or heated split/
splitless
4. Accessorize.
We have gas line installation kits for any type of gas
required for SRI GC systems operation.
Our internal "whisper quiet" air compressor can supply
FID air, air carrier, or detector makeup gas.
The methanizer accessory allows FID detection of CO and CO
2
down to the ppm range.
Although multiple injectors and detectors can be built into an SRI GC chassis, there are instances where certain
components would occupy the same space, or we simply run out of room. If you are not sure if everything you want will
fit, call one of our knowledgeable technical support agents for help. We may be able to make your dream system
