## Abstract A headspace solid‐phase microextraction (HS‐SPME) method coupled to GC‐MS was developed in order to determine trace levels of tetramethyltin (TeMT) and inorganic tin (iSn) after ethylation to tetraethyltin (TeET) in various matrices. The derivatization of iSn and the extraction of both
## Abstract We describe a simple and automatic method to determine nine aldehydes and acetone simultaneously in water. This method is based on derivatization with 2,2,2‐trifluoroethylhydrazine (TFEH) and consecutive headspace‐solid‐phase microextraction and gas chromatography‐mass spectrometry. Ace
