## Abstract In the present work, a method was developed and optimized aiming at the determination of anatoxin‐__a__ in environmental water samples. The method is based on the direct derivatization of the analyte by adding hexylchloroformate in the alkalinized sample (pH = 9.0). The derivatized anat

A reliable method for the characterisation of vodkas has been developed by application of solid-phase microextraction (SPME) and gas chromatography/mass spectrometry (GCMS). Sixty-four samples of commercial Canadian and American vodkas, and one sample each of Japanese and German vodkas, were investi
## Abstract Honey aroma is largely dependent on its volatile fraction, which in turn is influenced by nectar composition and by possible modifications after harvesting. Solid phase microextraction (SPME) allows a simple and rapid fractionation of volatile compounds in honey as a prior step to their
