A range of FID instruments are provided for continuous measurement
of hydrocarbons in air. Applications include emissions monitoring,
process and occupational exposure. More than 15 basic models are
manufacture by JUM located in Germany and distributed in the UK
by PPM.
The Detectors use a small flame, fuelled by Hydrogen or a Hydrogen-Helium
mix, to ionise a gas and give a current flow proportional to the
carbon content of the gaseous sample. The technique is extensively
used to report hydrocarbon concentrations and is the UK EPA recognised
methodology for emissions monitoring. The more sophisticated technology
uses a totally heated system (detector and sample transfer line)
to prevent any cold spots forming condensation affecting the integrity
of the sample.

The JUM design is renowned for the robustness and reliability of
the system. The use of a heated FID (detector, integral filter element
and transfer line) prevents condensation and the loss of volatile
organic compounds. The integral filter element (2-micron mesh) and
indeed the sample transfer line, can be automatically back-purged
to remove particulate and maintain good sample integrity. The burner
efficiency has also been optimised to give good oxygen synergism
that is of particular importance when measuring oxygen depleted
sample such as post incineration. No additional bottles of clean
air are needed since the design also integrates it own activated
filter on the burner air supply.
