Abstract An extremely simple, rapid method is described for simultaneously determining methanol, ethanol, acetone, isopropanol, and low-boiling hydrocarbons associated with glue sniffing. Less than 1 µl of blood, mixed with an internal standard, is injected directly into a low-cost gas chromatograph equipped with a flame-ionization detector. No extraction, distillation, and (or) sample preparation is required, and the method is sensitive to less than 10 µg of alcohol per ml.

Abstract A liquid chromatographic (LC) method was used to determine p,p'- and o,p'-isomers of dicofol AI (active ingredient) in Kelthane® EC and MF formulations. Samples are dissolved in methanol and AI components and impurities are separated on a high resolution C8 column in series with a short C18 guard column, with a methanol-water-acetic acid mobile phase. Cleaned samples are directly injected into the LC system and are monitored at 254 nm. Twelve collaborators submitted results on 5 samples. Using 95% confidence criteria, the average total standard deviation of the total AI across all samples was 2.82%. The method has been adopted official first action.
