Abstract

The review and re-fixing of an exposure limit value for carbon disulphide (CS2) faced problems, because several methods used in the past for the determination of carbon disulphide in the air gave only low reliabilities and systematic errors. The aim of a concerted action of the institution for statutory accident insurance and prevention in the chemical industry, the BG Institute for occupational safety (BIA), the German and Austrian chemical fibres industry and scientific experts was the improvement of the CS2 analysis in the air. One of the activities was the improvement of the desorption process of carbon disulphide from activated charcoal. The improved sample preparation was combined especially with high resolution gas-chromatography (GC) and mass spectrometry. Furthermore new methods were developed and validated for personal sampling of CS2. Several methods were compared in a proficiency test under real conditions. This led to higher reliabilities and a high comparability of the methods which use GC-procedures. It was shown that the reliabilities of photometric techniques were too low for the assessment of current exposure limits.
