Monitoring benzene for environmental compliance - Technical Bulletin
The Tiger Select is designed to allow specific detection of benzene in a complex mixture of hydrocarbons. This is done by drawing the sample through a Draeger benzene pre-filter tube. Typically benzene is monitored due to its health effects. As occupational Time-Weighted Average exposure limits are commonly set at 1 ppm or less, the benzene pre-filter tube has been tested primarily in the 0 to 40 ...
