The increasing demand for enantiopure drugs has led to the development of a variety of stereoselective separation technologies. Among them, high performance liquid chromatography (HPLC) is well recognized as a powerful, fast and efficient technique, which has been successfully employed for analysis and preparation of enantiomers of drugs. Nowadays, liquid chromatographic techniques are the focu...
Chemical speciation is a very important subject in the environmental protection, toxicology, and chemical analytics due to the fact that toxicity, availability, and reactivity of trace elements depend on the chemical forms in which these elements occur. Research on low analyte levels, particularly in complex matrix samples, requires more and more advanced and sophisticated analytical methods an...

Most hyphenated analytical approaches that rely on liquid chromatography-MS require relatively long separation times, produce incomplete resolution of oligosaccharide mixtures, use eluents that are incompatible with electrospray ionization, or require oligosaccharide derivatization. Here we demonstrate the analysis of heparin oligosaccharides, including disaccharides, ultralow molecular weight ...
Indigenous System of Medicine is gaining more and more attention towards its use allover the world, due to fewer side effects and less cost. Quality control of these medicines is the prominent part of this system of medicine for modernization and globalization. There are various analytical techniques available presently and screening of bioactive markers and compounds having therapeutic effects...
