This method is used for the determination of methyl acetate by GC/FID. This method employs a simple desorption with carbon disulfide and may be adapted for other esters with appropriate changes in chromatographic conditions. Improved recovery of analyte may be achieved with the addition of 5% butyl carbitol to the desorption procedure. The working range is 0.3 to 1330 ppm (1 to 440 mg/m³) for a 7 L air sample. NOTE: This method revises Method S42.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
