个人简介

A new method has been developed to measure the specific rotation of optically active compounds using flow injection as a sample introduction system. The laser-based Polarimetry for the detection and identification of chiral molecules was demonstrated by a study of the antibiotic: gentamicin. In addition, the determination of the specific rotation of several different amino acids and the corresponding peptides under different conditions of pH has been accomplished. These results have shown that specific rotation measurements can be used to monitor subtle changes in the structure of a complicated molecule. The use of laser-based polarimeter as a selective detector for optically active compounds has been extended to the detection of achiral compounds.
