ABSTRACT:
High pressure liquid chromatography apparatus for use in the analysis of optically-active materials comprises a semiconductor laser diode radiation source 10, a test sample holder 13 through which radiation from the radiation source passes to a detector 16. A polariser 11 and analyser 15 cooperate with a modulator 12 which modulates the rotation of the polarisation of radiation from the laser.
