Analytical Testing of Nitrosamines in Drugs and Food (April 2023)

In the second part of our interview, Novartis's Martina Lioi talks about using IP-HILIC and RP for lipid-siRNA impurities

LCGC International spoke to David Hage, Sanduni Heenkenda, and Zoe Zingler of the University of Nebraska-Lincoln about how green chemistry principles are reshaping affinity chromatography.

Panelists identify the parameters that make or break peptide method robustness and tech transfer, including temperature, flow rate, and dwell volume.

In Part 2 of "Conversations with Michael Dong," the LCGC column editor discusses HPLC columns for pharmaceutical analysis and the case for short columns.

Gas chromatography-mass spectrometry (GC–MS) shows scarlet macaw feather scent varies by sex and mate status.

Martina Lioi pairs IP-HILIC and RP to map impurities in fatty acid–linked siRNAs

Gas chromatography-mass spectrometry (GC–MS) reveals bisphenol A and other lasting pollutants in Maricá Lagoon (Brazil) sediments.

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.
