Abstract
The development by Grab and Habaich of a headspace
analytical technique which organic volatiles are trapped in
short capillary traps coated with a layer of fine activated charcoal
particles (COTs) or a layer of a suitable stationary phase (FTs), has
made it possible to perform headspace analyses on almost any
capillary gas chromatograph without having to invest in expensive
headspace sampling equipment. In this method the organic
material retained on a capillary trap is thermally desorbed in the
injector of the gas chromatograph and transported onto the
capillary column the carrier gas. A detailed description of the
application of this technique to the analysis of air and headspace
samples has recently been given by Grob et al. and it has also
been used for the GC-MS analysis of plant volatiles. Desorption
of thermally labile compounds from activated charcoal traps can
also be carried out with a few microliters of a suitable solvent such
as, for example, dichloromethane.
