Special Issues
Ultrahigh-pressure liquid chromatography (UHPLC) is a technique that is experiencing continued growth due to the benefits in separation power and speed of analysis over traditional HPLC. We attempt here to give an overview of some of the advances that have occurred in UHPLC since 2003, from the standpoint of both fundamental research and the introduction of commercially-available technology.
Common Challenges in Nitrosamine Analysis: An LCGC International Peer Exchange
April 15th 2025A recent roundtable discussion featuring Aloka Srinivasan of Raaha, Mayank Bhanti of the United States Pharmacopeia (USP), and Amber Burch of Purisys discussed the challenges surrounding nitrosamine analysis in pharmaceuticals.
Extracting Estrogenic Hormones Using Rotating Disk and Modified Clays
April 14th 2025University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).
