Purgeable Volatile Halogenated Hydrocarbons and Their Characteristic Masses... 

Table 2.9.1 lists some commonly used volatile halogenated hydrocarbons. Most of these are U.S. EPA listed pollutants. The term volatile indicates that these substances may be extracted by purge and trap technique. This also includes a few compounds of relatively moderate boiling range, responding adequately to the purge and trap method. The characteristic masses for GC/MS determination are also presented in the table. 

At this point, the sample is analyzed by gas chromatography (GC), the analytical method of choice for volatile halogenated hydrocarbons. Information on the analysis of these samples by GC is presented in Section 6.2, with a discussion of the advantages and disadvantages of each method. The technique of Antoine et al. (1986) showed a 5% variance on a series of 2 ppb spiked samples, and the analysis had a linear response ranging from 0.5 to 50 ppb. Although infra-red spectrometry has less sensitivity than electron capture detectors (ECD), Hall electroconductivity detectors (HECD), and mass spectrometrlc detectors (MS), it has been used to quantify the levels of... 

Gas chromatography-mass spectrometry has been applied to the determination of other types of orgaruc compounds in waste waters including the following (Table 16.9) hydrocarbons, phenols, organic halogen compounds, polychlorobiphenyls, chlorophenols, chlorinated tyrosine, nitrosamines, alkyl benzene sulphonates, N,N dialkyldithio-carbamates, volatile organic compounds.
