Abstract
Gas chromatographic methodology has been developed for quantitative analysis of samples of o-, m-, and p-ethylphenols. Samples are dissolved in a dichloromethane solution of the internal standard, anisole, and are then derivatized with N-trimethylsilylimidazole to form the silyl ethers. The samples are chromatographed with similarly prepared standards on a stainless-steel OV-17 support-coated open tubular (SCOT) column. Specificity, linearity, precision and stability of the samples are discussed, and chromatograms obtained on the SCOT column are compared to those obtained on a packed analytical column. This report describes one of the first quantitative gas chromatographic analytical methods to use a SCOT (capillary) column.
