Following a detailed study, a rapid and sensitive assay for the naturally fluorescent collagen cross-links pyridinoline and deoxypyridinoline has been developed using ion-pair reversed-phase high-performance liquid chromatography in the presence of 1-octanesulphonic acid (OSA). Pyridinoline and deoxypyridinoline were separated on...

We have observed dual transitions in various physical properties while investigating the surfactant-like behavior of the ionic liquid (IL) 1-butyl-3-methylimidazolium octylsulfate [C(4)mim][C(8)SO(4)] in aqueous media. Interestingly, in conductivity measurements, it was found that the second transition, which is comparatively weak...

By the introduction of trimethylammonium groups at both upper and lower rims, a cationic water-soluble pillararene was prepared, which forms a stable 1 : 1 host-guest complex with sodium 1-octanesulfonate in water.

The aim of this study was to develop a method based upon electrokinetic chromatography (EKC) using oppositely charged surfactant vesicles as a buffer modifier to estimate hydrophobicity (log P) for a range of neutral and charged compounds. Vesicles were formed...

Studies were carried out for the separation of uranium (U) and thorium (Th) on reversed-phase (RP) C18 columns using mandelic acid as an eluent. Retention of thorium-mandelate on the unmodified stationary phase was found to be greater than that of...
