## 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

## Abstract A sensitive and rapid derivatization method for the simultaneous determination of 1,3‐dichloro‐2‐propanol (1,3‐DCP) and 3‐chloropropane‐1,2‐diol (3‐MCPD) in water samples has been developed. The aim was to research the optimal conditions of the derivatization process for two selected re
## 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
## Abstract A method for quick and reliable analysis of cholesterol oxidation products (COPs) in dairy products has been developed. After lipid extraction, fat was transesterified under mild conditions to avoid degradation of the target compounds. Isolation of the COPs studied from other components
