Selectivity Semivolatile organic compounds

This particular demonstration module only incorporates decisions involving analysis of volatile and semivolatile organic compounds from water. These compounds are, by definition, volatile enough to be separated by gas chromatography (GC). The complete expert system will incorporate decisions based upon any type of chemical in any type of matrix and will also be capable of providing advice specifically for selected EPA methods commonly in use, i.e., EPA Methods 624, 625, 1624, 1625, the various non-mass spectrometric 600 Methods, etc. (Figure 1).

A selected list of semivolatile organic compounds was used to assess the effectiveness of the filtration unit. The analytes consisted of all quantifiable semivolatile compounds detected in the feed. 

GC is the most widely used instrumental technique today for quantitative organic chemical analysis for its unparalleled resolving power and sensitivity of detection, combined with relative simplicity of operation. The concept is based on the selective interaction of gaseous or semivolatile compounds (analytes) with the column packing or film as the vaporized...
