A method has been developed for the direct determination of paraquat and diquat in water samples. No sample preparation was required and analysis was done using high performance liquid chromatography coupled with ionspray tandem mass spectrometry. Heptafluorobutyric acid was used as the ion-pair age
Techniques are described for the pyrohydrolysis of a range of sample materials in a silica tube furnace. Samples are mixed with a catalyst and combusted at 1200ยฐC in a stream of oxygen and steam, and the liberated fluorine is absorbed in solutions appropriate to either ion-selective electrode or ion
