Abstract
The method is described for determining methyl-chloride (74873) in the air, including the principle, range and sensitivity, interferences, precision and accuracy, advantages and disadvantages, apparatus, reagents, calibration and standards, and calculations. The principle is based upon gas chromatography of samples collected on activated coconut charcoal with desorption with methylene- chloride. The range is 59-220ppm for an eight hour time weighted average and 143-580ppm for peak detection, with a precision of 0.052 (coefficient of variation). The OSHA standard is 100ppm eight hour time weighted average, 200ppm for a ceiling concentration, and 300 ppm for a peak concentration.
