Capillary electrophoresis (CE) with indirect UV detection is an interesting analytical method for the analysis of drugs and pharmaceuticals. Good and reproducible capillary quality is needed to develop robust methods and to facilitate method transfer in CE. It is widely accepted that preconditioning procedures are indispensable in capillary electrophoresis in order to achieve reproducibility of...

an environmentally benign rp-hplc approach for rapid analysis of glibenclamide in pure form, developed nanoemulsion and commercial tablets was developed and validated in present investigation. the green chromatographic identification was performed on lichrosphere 250 x 4.0 mm rp c8 column having a 5µm packing as a stationary phase using a combination of ethanol: methanol (50:50 % v/v) as a mobi...

A low-power laser-UV microbeam of wavelength 257 nm was used for microirradiation of a small part of the nucleus of Chinese hamster cells. Following fixation in interphflse or in the subsequent metaphase indirect immunofluorescent staining was performed with antiserum to photoproducts ofDNA treated with far UV ligh t. The results show that antibodies specific for UVirradiated DNA can be used fo...

A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, N-methyl-2,2'-dipyridinium iodide and N,N'-dimethyl-2,2'-dipyridinium diiodide, were used as the visualization reagents, forming ion-pair complexes with the sulfonate surfactants. This a...
