| Abstract: | his certified reference material (CRM) of benzene,toluene and o xylene in charcoal is used for quility control and calibration of analytical instruments in the determination of benzene,toluene and o xylene in air.Homogeneity of benzene,toluene and o xylene concentrations in the CRM was testes by GC.The stability of the CRM was assessed for one year.The certified values are based on analysis made by a group of independent laboratoies using GC method. |
