The
Model 4020 utilizes a flame ionization
detector (FID) for the continuous trace
analysis of total hydrocarbons (THC)
under a variety of different process
conditions. The principle of operation
is based on measuring the ion current
generated when organic compounds are
dissociated in an intense hydrogen flame.
The
4020 is ideal for monitoring hydrocarbon
contamination in high purity bulk gases.
When coupled with Teledyne's unique
separation column, the 4020 is also
diverse enough to be applied in hazardous
locations for the detection of volatile
hydrocarbons in cooling water for process
leak detection and environmental compliance.
Gas
Control System
- Unique
sintered stainless steel restrictors
control the flow of the sample and
support gases to provide a stable,
reproducible signal
