HPLC Detection and Evaluation of Chiral Compounds with a Laser-Based Chiroptical Detector
The sensitivity and ruggedness of chiroptical detectors have improved considerably during the past decade. In this article, the authors examine more than 230 chiral compounds using the latest laser-based polarimetry detector for high performance liquid chromatography (HPLC). They also examine the relationship between optical rotation at the detector wavelength of 675 nm and the sodium D line. In addition, the authors consider the sensitivity, linear dynamic range, and effect of solvent composition on rotation and its general use as an HPLC detector for chiral compounds.

LCGC’s Year in Review: Highlights in Liquid Chromatography
December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.
Mobile Phase Buffers in Liquid Chromatography: A Review of Essential Ideas
December 11th 2024In this installment of "LC Troubleshooting," Dwight Stoll discusses several essential principles related to when and why buffers are important, as well as practical factors, such as commonly used buffering agents, that are recommended for use with different types of detectors.
