Ambient air. Determination of total non-methane organic compounds. Cryogenic preconcentration and direct flame ionization detection method has-digital BS EN 15152 is also1 Scope This International Standard describes a procedure for sampling and determining concentrations of total non methane volatile organic (NMVOC)in the ambient atmosphere. This International Standard describes the collection of cumulative samples in passivated stainless steel canisters and subsequent laboratory analysis. It describes a procedure for sampling in canisters at final pressures above atmospheric pressure (referred to as pressurized
