✦ Synopsis

Soil fumigants, like 1,3-dichIoropropene and metham-sodium (forming methyl isothiocyanate) diffuse into the atmosphere, thus presenting a hazard to people in the surroundings. A method is described in which a large volume (50 PI) of extractant, used to desorb the compounds from charcoal, is injected into a GC, equipped with two capillary columns. By way of Deans switching, the solvent is separated from the compounds of interest. Modification of a GC sampler makes unattended analyses possible.

Gas chromatography/tandem mass spectrometry (GC/MS/MS) using an ion-trap instrument was applied for the determination of ergosterol, muramic acid and 3-hydroxy fatty acids with 10-18 carbon atoms in samples of organic dust. These substances were used as chemical markers to measure fungal biomass, ba

## Abstract A novel approach to the determination of 17β‐estradiol in bovine plasma is presented. The observed enhanced sensitivity is gained by the application of tandem mass spectrometry (MS) fragmentation to a stable, well characterized negative ion produced by chemical ionization (methane as re
