Sl.No. Synosis Points
1 This method is applicable to measuring the vapour-fraction of GC-compatible organic compounds in ambient, indoor and workplace air and in the air exhausting from product or material emission test chambers. Compatible compounds range in volatility from C3 to n-C30 hydrocarbons at concentrations ranging from low micrograms per cubic metre (low ng/l) to milligrams per cubic metre (high µg/l).
