Heptachlor Analytical Method.
NIOSH 1978 Jan:30 pages
The NIOSH analytical method S287 for determining heptachlor (76448) in air is described. Samples are adsorbed on Chromosorb-102 (9003707), desorbed with toluene (108883), and analyzed by gas chromatography with an electron capture detector. The working range of the method is 0.23 to 1.0 milligram per cubic meter, the coefficient of variance is 0.066, and the detection limit is about procedures are described, and calculations are provided for determining sample concentrations. Data on collection efficiency, and recovery, stability and breakthrough rates is included.
