The 2024 Gulf Coast Conference will include a variety of presentations on chromatography. This article features a sampling of some upcoming sessions.

Julien Crepier of TotalEnergies was one of the researchers that conducted this study, and he recently sat down with LCGC International to talk about his team’s findings.

In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.

A recent study focused on improving the flavor of beef from Xinjiang brown cattle utilized two-dimensional gas chromatography–time-of-flight mass spectrometry (GC×GC-TOF MS to analyze volatile flavor compounds across different beef cuts.

Abacavir and Lamivudine in combination are used with other medications to treat Human Immunodeficiency Virus (HIV) infection. In this technical note, we report the separation of Lamivudine from its related chiral and diastereomeric impurities in Abacavir and Lamivudine tablets per the USP monograph. The allowable adjustments pertaining to gradient separations are highlighted together with the necessary calculations that are required for the adjusted method conditions to remain compliant with the original monograph.
