A novel method for speciation analysis of inorganic arsenic was developed by on-line hyphenating microchip capillary electrophoresis (chip-CE) with hydride generation atomic fluorescence spectrometry (HG-AFS). Baseline separation of As(III) and As(V) was achieved within 54 s by the chip-CE in

Reduction with [3H]KBH4 of Schiff's bases generated by reaction with pyridoxal 5'-phosphate (which cannot penetrate the intact cytoplasmic membrane) yields tritium-labeled derivatives of both proteins and lipids accessible on the periplasmic side of the cytoplasmic membrane. Application of this technique

A new method is proposed for simultaneous determination of traces of arsenic (As) and selenium (Se) in biological samples by hydride-generation double-channel non-dispersive atomic-fluorescence spectrometry (HG-AFS) from tartaric acid media. The effects of analytical conditions on fluorescence signal intensity were

Carboxyatractyloside was labeled with [3H]KBH4 after oxidation of the primary alcohol of the glucose disulfate moiety by dicyclohexylcarbodiimide and P2O5 under anhydrous conditions in a dimethylsulfoxide medium. The 3H-labeled product was purified by DE 52 column chromatography followed by Cellulofine
