Round robin tests for determination of organic solvent vapours in air with charcoal tube samplers

Abstract

Round robin tests were carried out for the investigation about the precision of charcoal tube samplers for determination of organic vapours in the industrial atomosphere. Eight artificial gas samples contained two or three constituents of organic solvent vapour were used. Charcoal tube samplers collected these gases were distributed to 2025 laboratories and the results were compared with respect to mean values, relative standard deviation and accuracy. The satisfied results were obtained for the storage and the recovery of samples with the charcoal tube samplers.
