• Conventional sample back pressure regulator (BPR)
• 19-inch slim line design, 132mm high
• Automatic flame out indicator with automatic fuel shut off valve
• Fast response
• Low fuel and air consumption
• Very selective
• All heated components in oven, except BPR
• Microprocessor PID-type temperature controller for FID-oven

• Detection of low trace hydrocarbon levels in high purity Hydrogen Gas
• Online inspection of high purity Hydrogen plumbing systems as used in the semiconductor industry
• Online monitoring on loading terminals for hydrocarbon contamination in Hydrogen

The J.U.M. Engineering HFID Model H100 is a compact 19' rack mount or table top heated FID analyzer for the measurement of low trace total hydrocarbon concentration in Hydrogen. High accuracy, high sensitivity and good stability are reached with the FID housed in a heated oven.

The Model H100 is ideally suited for the detection of very low traces of hydrocarbons in pressurized high purity Hydrogen gasses. H100 may also be well suited for the integration in low concentration Hydrogen online inspection systems.

The Flame Ionization Detection (FID) method is used to determine the presence of total hydrocarbon concentrations in a gaseous sample:

Burning hydrocarbon-free hydrogen in hydrocarbon-free air produces a negligible number of ions.

Once a sample containing hydrocarbons is introduced into this flame a very complex ionization process is started. This process creates a large number ions. A high polarizing voltage is applied between the two electrodes around the burner nozzle and produces an electrostatic field. Now negative ions migrate to the collector electrode and positive ions migrate to the high voltage electrode. The so generated ionization current between the two electrodes is directly proportional to the hydrocarbon concentration in the sample that is burned by the flame. This signal is measured and amplified by our electrometer-unit.

A conventional sample back pressure regulator creates a constant back pressure to the sample capillary which provides constant sample gas flow to the detector.

Our compactly designed flow control module for controlling the fuel and air flow rates via needle valves use high precision pressure regulators. The needle valves are factory adjusted and sealed to ensure the optimization of the burner.
