Determination of airborne dioxitol vapour by charcoal tube sampling and gas-liquid chromatographic analysis
Abstract
A procedure is described for monitoring airborne dioxitol vapour. The vapour is adsorbed on to charcoal, desorbed with methanol-dichloromethane (5 + 95, V/V) and analysed by gas-liquid chromatography. The calibration graph is linear up to 990 µg of dioxitol and the desorption efficiency of the solvent is 100%. The repeatability of the method is better than ±10%.
