Rapid, Sensitive LC–MS-MS Analysis of Nicotine and Metabolites

This week, Chromatography Online covered automated GC-MS/MS testing for phthalates in oils, chemicals hidden in bioplastic packaging, troubleshooting tips for oligonucleotides and GLP-1 peptides, automated glycan profiling, NIST reference materials, and the experience of being the only woman in the laboratory.

Multidimensional chromatography cuts ion suppression in complex environmental samples by separating salts and coeluting compounds from target analytes.

The panel discusses quantitative peptide analysis, including drug substance vs. drug product complexity, recovery, and methionine oxidation risk.

Gas chromatography–quadrupole time-of-flight mass spectrometry (GC–QTOF MS) screening of dust finds 269 contaminants in homes, offices, and schools.

The 2026 Gulf Coast Conference (GCC) will be held at the Moody Gardens Convention Center in Galveston, Texas, from October 12–15.

The panel cover protecting peptide recovery, from mobile-phase pH and diluent buffers to inert column hardware.
