Trace analysis of alkylbenzenesulphonates in river water has been itivestigated by combined gas-liquid chromatography-mass spectrometry. Methylene blue-alkylbenzenesulphonate complexes are first formed and then extracted with chloroform. The methylene blue is removed and the alkylbenzenesulphonates

A gas chromatographymass spectrometric method for determination of unsymdimethylhydrazine (UDMH) in soil and water has been developed. The method is based on derivatization of UDMH with 2-nitrobenzaldehyde, 4-nitrobenzaldehyde, 4-chlorobenzaldeyhde, 4-cyanobenzaldehyde, 4-dimethyaminobenzaldehyde, b
In order to estimate photosynthetic and respiratory rates in illuminated photoautotrophic cells of carnation (Dianthus caryophyllus L.), simultaneous measurements of CO2 and 02 gas exchange were performed using 1802, 13CO2 and a mass-spectrometry technique. This method allowed the determination, and
