Description:
The J.U.M. Engineering HFID Model 3-300A is
a very compact 19" rack mount heated total hydrocarbon analyzer
for high accuracy, sensitivity and stability and uses a hydrogen
flame ionization detector (FID) in a heated oven, which is heated
to 190°C to prevent the loss of high molecular weight hydrocarbons
and to provide reliable performance in the analysis of trace
level of contaminants in high purity gases, air and other gases.
All sample wetted components are integrated
into the heated chamber.
The permanent heated sample filter is cleaned
by backpurging and additionally has a replaceable stainless steel
2µm mesh filter disc. The burner air supply is built in.
No extra bottles for burner air are needed.
Our special rear adaptor-plate system allows
cold-spot free coupling of a heated sample line inside the heated
oven without the need of special tools.
