Benzalkonium chloride (BAK) is a common preservative composed of quaternary ammonium compounds with 8–18 carbon alkyl chains, mainly C12, C14, and C16 homologs. Because BAK can adsorb to surfaces, this study highlights the challenges of predicting adsorption behavior and the importance of conducting a vial compatibility assessment early in HPLC method development for dilute solutions of BAK and analytes with similar physicochemical properties.

Researchers at Oregon State University and Dow Neurobiology developed a standardized aroma lexicon for characterizing the aromatic attributes of Cannabis inflorescence with an associated sensory method that included the use of gas chromatography in data analysis.

LCGC International and the HTC-19 Scientific Committee celebrate innovation in separation science with the 2026 HTC Innovation Award. Previous winners include Bob Pirok, Szabolcs Fekete, Ryan Kelly and Caroline Huhn.

Researchers at the University of Buffalo used combined middle-up and bottom-up LC–MS/MS to characterize the HIV-1 broadly neutralizing antibody PGT 121. They identified multiple Fc and site-specific glycoforms and an unexpected N-terminal serine, revealing significant structural heterogeneity. This integrated approach enhances understanding of bNAb structure, supporting quality control and clinical development. LCGC International spoke to Troy Wood, corresponding author of the paper resulting from this research.
