J.U.M. Engineering has been established during late 1973 in Munich Germany. The company was started out of a perceived need of the industry for unbiased sample handling solutions in the automotive raw exhaust hydrocarbon gas emissions market and in the field of industrial hydrocarbon gas emissions.

During its first year, J.U.M. soon recognized the urgent need of the industry for easier to use heated sample filters. J.U.M. has successfully installed the first heated sample filter to be backpurged for cleaning. It was part of a conventional multi component analysis system for raw diesel exhaust emissions. At that time it appeared to us that the conventional way of heated gas emissions sample handling techniques had one basic flaw; each time an emissions test came nearly to its end, the hydrocarbon hang up already was way up and showed too high hydrocarbon concentration numbers. The user ended up with not good enough test results mostly in a situation, where he could not simply make the change of his contaminated sample filter without interrupting his test. J.U.M. also has early recognized the importance and the need for an easy to use rugged hydrocarbon FID analyzer where a sample filter change (of the internal filter) could not be tolerated during the test run.

During the first 18 months of its existence, J.U.M. has developed a heated sample filter with a built in filter backpurge feature. A patent has been filed and was issued for this product. Towards the end of 1974, we have introduced our first fully heated total hydrocarbon analyzer based upon a FID detector. This FID analyzer was already equipped with our proprietary high pressure backpurge sample filter system. This new type of an easy to use hydrocarbon analyzer was also equipped with our fail safe FID ignition fuel enrichment system which was the first in the industry.

Also in 1974, J.U.M. has successfully introduced a carbon adsorber based burner air supply (BAS) for gas chromatographs with FID-detectors and other analyzers with FID-detectors. This new and money saving product allowed FID users for the first time to operate their gas chromatographs or analyzers without the use of costly and bulky high pressure synthetic air cylinders. Several thousand of these BAS's are still in use all over the globe.

All of the J.U.M. total hydrocarbon analyzers are based upon our proprietary designed flame Ionization detector (FID) which is well recognized for its high sensitivity, long term stability and easy serviceability. Also all of our FID-analyzers are equipped with a still very unique permanent stainless back purge sample filter. To overcome known hydrocarbon condensation problems in THC analyzers, J.U.M. Engineering has developed a very special flow system in a heated oven. We have first introduced to the industry a sample pressure control system for highest sample flow rate stability and lowest maintenance without the use of the conventional sample back pressure regulator in the fall of 1974. Conventional back pressure regulators are highly effected by condensation products, and by heat. Still, for applications, where an undiluted sample bypass is still required, J.U.M. has developed a heated dome loaded sample back pressure regulator for high temperature applications in our FID-analyzers during 1984 / 85.

In 1988, J.U.M. has introduced its first methane only FID-analyzer which allowed to continuously measure non methane hydrocarbon emissions (by using J.U.M.'s proprietary non methane hydrocarbon cutter design) in conjunction with another standard FID analyzer.

In 1990, J.U.M. Engineering has introduced the first working heated FID analyzer in the industry with our proprietary internal dual pump bypass system design. This analyzer is completely unaffected by pressure fluctuation at the sampling point. It is also capable to deliver hot and wet sample to other gas analyzers without the need for a separate sampling system.

In 1991, J.U.M. introduced the first working heated non methane hydrocarbon analyzer by using our dual detector/ dual electrometer technique in conjunction with our proprietary non methane hydrocarbon cutter design.

In 1994, J.U.M. has introduced the first working, easy to operate heated FID-analyzer for the continuous measurement of total hydrocarbons in live hot or wet steam. This analyzers uses a newly developed proprietary internal sampling method to extend up time and accuracy.

In 1998, J.U.M. introduced the first working heated non methane/non ethane hydrocarbon analyzer by using our dual detector/ dual electrometer technique in conjunction with our proprietary non methane hydrocarbon cutter design.

In the first quarter of the year 2000 J.U.M. introduced it´s first fully microprocessor controlled FID analyzer. Based upon our proven FID Model 3-300A it meets all requirements of EPA Method 25A, 17. BImSchV, 13. BImSchV and 2. BImSchV.

With a background of having more than 5000 FID-analyzers in the field, J.U.M. today tailors its heated total hydrocarbon analyzers for nearly every THC application in the industry by using the well proven building blocks from our large range of more than 15 different basic FID analyzers. We also manufacture a broad range of heated sample filters and sample interface modules for the stack gas emissions industry and the automotive industry. All three of our basic total hydrocarbon analyzer models (VE7, 3-300A and 3-200) are TÜV approved to meet all standards of TA Luft, 17. BImSchV, 13. BImSchV and 2. BImSchV. These analyzers also are approved to meet the North American standards of EPA-Method 25A and EPA-Method 503. A superb network of sales representatives, most with factory certified service departments throughout Europe, internationally, and in the US guarantees best possible service.

Today J.U.M. custom fits total hydrocarbon analyzers for nearly every THC application in the industry by using standardized modules from our broad range of more than 15 different basic HFID analyzers.

J.U.M Engineering has achieved and maintained a leadership position by continually increasing the scope of its expertise and by producing dependable, sophisticated products that meet current accepted standards. J.U.M. Engineering hydrocarbon emissions monitoring products meet specifications established by the US Environmental Protection Agency (EPA) for stationary hydrocarbon source monitoring apparatus and for the German Umweltbundesamt.
