Monitoring Benzene

This presentation talks about monitoring of Benzene in the Ambient Air by using ORGANIC VAPOUR SAMPLER APM 856. A known volume of air sample is passed through a tube packed with Activated Charcoal or Tenax. The organic vapors are adsorbed on the charcoal. • The collected vapors are desorbed using a suitable solvent like CS2 and analyzed with the help of a Gas Chromatograph. With the APM 856 Samples averaged over several hours can be collected making it possible to compare values obtained with Standards.
