| Abstract |
A technique is described which allows collection and analysis of a range of volatile organic emissions from automotive painting operations in a single procedure. Glass charcoal tubes were spiked with a mixture of paint solvents dissolved in carbon disulfide (CS2). The adsorbed compounds were desorbed with either CS2 or a mixture of CS2 and dimethyl sulfoxide (DMSO). Analysis was carried out by gas chromatography. An extraction solvent consisting of 4% DMSO in CS2 gave a satisfactory recovery (higher than 80%) for many commonly used paint solvents. This procedure has an advantage over current standard methods that may require multiple extractions. |
