Fluorinated Monolithic Columns for LC
Researchers from Queen's University (Kingston, Ontario, Canada) developed porous polymer capillary columns with varied flurous content for chromatography of tagged analytes.
Researchers from Queen's University (Kingston, Ontario, Canada) developed porous polymer capillary columns with varied flurous content for chromatography of tagged analytes. They used a UV-initiated radical polymerization process to create the monolithic columns and tested them using flow-induced back pressure and scanning electron microscopy. The columns were able to separate fluorous-tagged analytes under gradient conditions, and the researchers found that the fluorinated monolithic columns exhibited greater selectivity for fluorous analytes than did comparable nonfluorinated monolithic columns.
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.
