halogen-specific detector for the analysis of halogenated volatileorganics including vinyl chloride in solid waste. Under the prescribedconditions for vinyl chloride, the method has a detection limit of 0.18ug/l. Precision and method accuracy were found to be directly related tothe concentration of the parameter and essentially independent of thesample matrix. [USEPA; Test Methods for Evaluating Solid Waste SW-846(1986)]**PEER REVIEWED**EPA Method 8240. GC/MS for the determination of volatile organics. Thismethod can be used to quantify most volatile organic compounds includingvinyl chloride that have boiling points below 200 deg C and are insolubleor slightly soluble in water. The detection limit is not given. Precisionand method accuracy were found to be directly related to the concentrationof the analyte and essentially independent of the sample matrix. [USEPA;Test Methods for Evaluating Solid Waste SW-846 (1986)]**PEER REVIEWED**EPA Method 601. Purge and Trap GC with electrolytic conductivity detectionfor the analysis of purgeable halocarbons including vinyl chloride inmunicipal and industrial discharges. Under the prescribed conditions, themethod detection limit for vinyl chloride is 0.18 ug/l. The method isrecommended for use in the concentration range from the method detectionlimit to 1000 times that limit. Precision and method accuracy were foundto be directly related to the concentration of the parameter andessentially independent of the sample matrix.

Under the prescribed conditions for vinyl chloride, the methoddetection limit is not given. Precision and method accuracy were found tobe directly related to the concentration of the parameter and essentiallyindependent of the sample matrix. [40 CFR 136, App. A (7/1/90)]**PEERREVIEWED**EPA Method 1624. Isotope Dilution Purge and Trap GC/MS. This method isapplicable for the determination of volatile organic compounds inmunicipal and industrial discharges. By adding a known amount of anisotopically labeled compound to every sample prior to purging, acorrection of recovery of the pollutant can be made. If isotopicallylabeled compounds are not available, an internal standard method is used.Under the prescribed conditions for both the isotopically labeled andunlabeled vinyl chloride the method has a minimum detection level of 50and 10 ug/l with no interferences present.

Purge and Trap GC/MS for the determination of volatilearomatic compounds in finished drinking water, raw source water, ordrinking water in any treatment stage. For vinyl chloride the method has adetection limit of 0.17 ug/l and a relative standard deviation of 6.7%with a wide bore capillary column, and a method detection limit of 0.04ug/l and a relative standard deviation of 0.2% with a narrow borecapillary column.
