Enhanced Polarimetric Detection in HPLC Using a Refractive Index Equalizer

Pseudorotation effects in polarimetric detectors for high-performance liquid chromatography are examined, and a method to actively reduce these distortions is presented. In the method, the refractive index of the eluents is maintained at a constant value by mixing a variable amount of a second, opti...

Zusammenfassung:Pseudorotation effects in polarimetric detectors for high-performance liquid chromatography are examined, and a method to actively reduce these distortions is presented. In the method, the refractive index of the eluents is maintained at a constant value by mixing a variable amount of a second, optically denser phase.
