J.U.M. - Model 3-800 -Portable Heated Total Hydrocarbon Analyzer
The J.U.M 3-800 Portable Heated Total Hydrocarbon Analyzer is a heavy duty FID analyzer to continuously measure the total concentration of hydrocarbons within a gaseous sample. This can be ambient air, exhaust gases from a combustion process e.g. stack emissions, from any type of an industrial vent, from an internal combustion engine, or from any other emission containing hydrocarbons. The 3-800 fully complies with EN 12619, EN 13526, QAL 1 (EU), with 2. BImSchV, 13. BImSchV and 17. BImSchV, (Germany) and with EPA Method 25A and Method 503 (USA). It is ideally suited to be used in all stack emissions applications.

The J.U.M. Engineering HFID Model 3-800 is a low cost, portable and compact heated total hydrocarbon analyzer for high accuracy, sensitivity and stability.
The Model 3-800 uses a 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. The disposable heated sample filter is easily accessible from the rear panel and no special tools required for a quick and easy sample filter change. All sample wetted components are integrated into the heated chamber.
Our optional 50 liter metal hydrid fuel storage (See inserted picture) allows a 45 hour minimum of uninterrupted operation. This fuel storage can be very safely self-filled at a low pressure of 25 bar. No special adapter needed.
Low cost of ownership. Very low fuel gas consumption. The combustion air supply for the FID-detector is already built in. 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 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 is used by J.U.M. Engineering for over 30 years 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.
