0

The HFID Model 603 is a competitively priced, digitally controlled self extracting, heated total hydrocarbon analyzer for high accuracy, sensitivity and long term stability. It can be used in a 19' rack or as a table top instrument.

Standard features are automatic start-up with ignition, automatic and manual zero and span gas calibration, auto ranging, diagnostics and an optional data logger. Also standard is our 7 inch touch screen display with direct activation of all important functions without dialog

The Model 603 uses our time proven hydrogen flame ionization detector (FID) in a heated oven to prevent the loss of high molecular weight hydrocarbons and to provide very reliable performance in the analysis of trace level of contaminants in emissions, gases, air and other gases.

All sample wetted components are integrated into the heated chamber. The heated sample filter is easily accessible from the rear panel. No special tools are required for a quick and easy sample filter change.

Low cost of ownership. Very low fuel gas consumption. The combustion air supply for the FID-detector is already built in, so no external burner air generator or external cylinder for synthetic burner air is needed.

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 digital sample pressure regulator provides a controlled back pressure at the sample capillary which gives admittance of a constant sample flow rate to the burner. This technique without the conventional back pressure regulator was invented by J.U.M. Engineering in 1974 to provide the highest possible sample flow rate stability and lowest maintenance. 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.
