## Abstract A new allβglass interface for GC/MS designed to fully exploit the potential of glass capillary columns is described. The system works in the open split mode and has high versatility with respect to column changing. It is especially suitable for mass spectrometers, which are not exclusiv
## Time (mins) chromatogram of an extract of a 35 m3 air sample taken near a photocopying machine. The method described here for the measurement of TNF in air is fast and quantitative and will allow TNF to be measured at levels down to 0.1 pglm3, based on a 100 I air sample. ## References [I]
The static coating method forthe preparation of wall-coated, open tubular columns is used widely because of its simplicity. The
