Sampling and analytical methods for determining 1,2-dichloropropane (78875) (1,2-DCP) were evaluated. Detectors and columns were tested for suitability for chromatographic analysis. Various charcoals and other sorbents were tested for their capacity and desorption efficiency. An independent continuous organic vapor monitor was used to determine concentrations during the sampling studies. Petroleum charcoal was the most efficient collection medium, and acetone in cyclohexane was the most efficient desorbant. Gas chromatography with electrolytic conductivity was efficient for analysis. In tests over the concentration range of 0.124 to 128 milligrams per cubic meter , 1,2-DCP, the combination of petroleum charcoal, acetone in cyclohexane, and gas chromatography provided a 6.4 percent deviation for repeated measurements. Average recovery was 100 percent.
