NIOSH 1975:S382-1 - S382-9
A method of analysis for Stoddard-solvent (8052413) concentration in air is presented. The principle of the method is as follows. A known volume of air is drawn through a charcoal tube to trap the organic vapors present. The charcoal in the tube is transferred to a small, stoppered sample container and the analyte is desorbed with carbon-disulfide. An aliquot of the desorbed sample is injected into a gas chromatograph. The total area of the resulting peaks is determined and compared with corresponding areas obtained from injection of standards. Under the conditions of sample size (3 liters) the probable useful range of this method is 295-8850 milligrams per cubic meter at a detector sensitivity that gives nearly full deflection on the strip chart recorder for a 26.6 milligram sample. This method is capable of measuring much smaller amounts if the desorption efficiency is adequate. Desorption efficiency must be determined over the range used. Interferences, accuracy, advantages and disadvantages of the method are described.
