NIOSH Analytical Method, Benzene, S311, (Set U).
NIOSH 1976 Dec:8 pages
A method is described for the analysis of benzene (71432) in the air by drawing a known volume of air through a charcoal tube to trap the organic vapor present, followed by desorption of the analyte with carbon-disulfide, injection into a gas chromatograph and comparison of the area of the resulting peak with areas obtained for standards. Data are given on the principle, range and sensitivity, interference, precision, accuracy, advantages and disadvantages of the method. Also described are the apparatus, reagents, and procedures used, analysis of samples; interferences; calibration and standards; and calculations.
