  • C. A. KNUTSON
چکیده

An improved procedure for determination of composition of heteropolysaccharides by radiochromatography of sodium [3H]borohydride-reduced hydrolyzates has been developed. The method is accurate and sensitive, is less cumbersome and more reliable than similar procedures currently in use, and permits, for the first time, compositional analysis of hydrolyzates containing both hexoses and uronic acids in a single radiochromatographic procedure.

Physical separation of amphiprotic-polar aprotic solvents for simultaneous extraction and clean-up of clomiphene from plasma before liquid chromatographic analyzes

An efficient and quantitative two phase freezing (TPF) method coupled with high performance liquid chromatography and UV-Vis detector was developed for the extraction, clean up and determination of clomiphene citrate (CLC) in plasma samples. The separation of two miscible solvents by TPF method permits that the CLC was efficiently removed from proteins and transferred into the relative aprotic ...

Review High-performance liquid chromatographic enantioseparation of drugs containing multiple chiral centers on chiral stationary phases

In recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. High-performance liquid Chromatography is a very useful method for the direct separation of enantiomers. However, about 30−40 years ago, commercially available chiral stationary phases wer...

Enantiomer separation of a novel aminothiazolecarboxamide fungicide using polysaccharide-derived chiral stationary phases.

The direct enantioseparation of a novel aminothiazolecarboxamide fungicide, ethaboxam, on polysaccharide-derived chiral stationary phases (CSPs) is described. Good resolution is achieved with several polysaccharide-derived CSPs. Chiralcel OD (OD-H) and Chiralpak AS are excellent for direct enantiomer separation of ethaboxam. The elution behavior and the effects of eluent composition on the reso...
