Abstract

A polarization modulation polarimeter for a HPLC detector has been designed and constructed based on a principle, the electrical null-point detection method, which is entirely different from that of a commercially available polarimeters, the optical null-point detection method. The Mueller matrix method is used to analyze and evaluate important factors determining its performance. It is revealed that a crystal quartz Rochon prism must be used as a polarizer, and should be mounted on a rotatable stage equipped with a mechanism for precise adjustment to set its azimuth angle at 0 degrees as precisely as possible. Furthermore, all optical components used should have the least amount of the residual static birefringence. The total performance of our polarimeter is found to be equivalent to that of commercially available polarimeters.
