摘要：

Detecting changes in magneto-optical rotation is useful as a universal on-line detector for high-performance liquid chromatography. Such apparatus is similar to a polarimeter except for the external magnetic field on a flow cell. Two modulation modes suitable for the magneto-optical rotation detector are discussed. Use of a semiconductor laser provides better sensitivity than a He-Ne laser. The detection limit is 0.006% (w/w) for polyethylene glycol 20000 in a 20-mu-l injection.
