Development of a gaschromatography measurement technique for determining the content of hexane in the air at the workplace

Project No. BG18 #004


completed 03/1998


Air-contamination by hexane used in extraction at work places in oil mills. Goal: elaboration of a gaschromatography measuring technique for work place monitoring


Work area analysis in five oil mills, ambient and personal air monitoring performed in the extraction or distillation area in accordance with technical rule (TRGS) 402


All procedural and substance-specific criteria for individual extraction processes were investigated. During continuous extraction processes the concentrations of n-hexane were less than 1/4 of the threshold limit value (in normal operation). During intermittent processes the values were about half the threshold limit value.
