Abstract

Personal monitoring of exposure to potentially harmful vapours is legally required. It is meaningful only if the results are accurate. It is often taken for granted that less than 20 % error upon sampling and less than 10 % error upon analysis are easily achieved. Intercomparisons with leading laboratories from government and from the chemical industry, however, have shown much larger errors on several occasions. Therefore, a project providing the means to measure quality control in this area was started in the framework of the BCR-programme. For sampling, a series of intercomparisons was started in which participants sample the same air, of known composition, using their own sampling system. For analysis, a certified reference material was developed with 1 microgram of benzene, toluene and m-xylene in stainless steel tubes containing tenax. Other CRMs are in preparation for thermal as well as solvent desorption.
