A sampling and analytical method for vinyl-bromide (593602) determination in air was developed. The method involved use of solid sorbent, coconut based charcoal, desorption of the analyte with absolute ethanol, and gas chromatography/flame ionization detection. Air samples containing vinyl-bromide in concentrations ranging from 1.32 to 56.5 milligrams per cubic meter (mg/CuM), were used to evaluate the procedure. Two alternative extraction procedures were presented: continuous and multiple extraction. Vinyl-bromide was separated from ethylene, acetylene, and 1,3- dibromoethane samples, but not from bromine. Recovery of vinyl- bromide was 90 percent. The method allowed a precision of 9.0 percent Relative Standard Deviation (RSD) over the vinyl-bromide concentration range of 1.32 to 6.38 milligrams per cubic meter (mg/CuM) and 6.3 RSD over the range of 6.38 to 56.5 mg/CuM.
