Ozone precursor analyzer Synspec GC955 models 615 and 815
Toxic hydrocarbons can enter the atmosphere as part of the emissions of industrial enterprises for the production of polymers, drugs, oil refining, etc. This analyzer is designed to measure the content of hydrocarbons that have toxic and / or carcinogenic properties, as well as those involved in the formation of ozone.
System 615 is a gas chromatograph with an integrated sample pre-concentration system. The hydrocarbons are concentrated on a Tenax GR carrier, thermally desorbed and separated on a DB1 column, thus achieving optimum separation of the interfering hydrocarbons. For detection, flame ionization and photo-ionization detectors are used.
The system 815 is a gas chromatograph with a built-in cooled preconcentration system. Hydrocarbons at 5 ° C are concentrated on a Carbosieves SIII carrier, thermally desorbed and separated on a system consisting of two columns: with a pellicular and a surface porous (PLOT) sorbent, which makes it possible to separate low boiling hydrocarbons. For detection, flame ionization and photo-ionization detectors are used.
The basic set for toxic hydrocarbon measurements Synspec 615 offers a list of hydrocarbons, for which the system is configured by default. However, some toxic hydrocarbons have low boiling points and can not be determined in cases where the GC 615 system alone is used. This problem can be solved by using the 615/815 combined system.
