摘要:
A desorption-injection apparatus providing a convenient inexpensive means to transfer preconcentrated volatile mixtures from a sorbent polymer trap onto a GC column without interruption of the operation of the gas chromatograph is described. Thermal desorption is accomplished by resistive heating of a stainless steel trap. Performance of the apparatus was evaluated with data from a known volatile mixture obtained by both desorption-injection and by direct injection.
