Abstract
The analysis of volatile organic compounds at low concentrations (ppb or ppt) is performed by making a sample flow to pass through a cold trap containing few mg of packing, at a sample feeding speed ranging between 50 and 1000 cm/sec; the sample thus concentrated is then desorbed by heating of the trap and conveyed for the analysis.
