The October 2025 FDA draft guidance for biosimilars marks a major shift toward greater reliance on analytical data. Most notably, it signals a move to reduce or even eliminate comparative efficacy studies when robust analytics can provide equivalent insight, detecting subtle differences that clinical studies often miss. Biosimilar development will continue to require comprehensive analytical packages, with emphasis on orthogonal techniques. This session features Colette Quinn from Waters Corporation, who discusses how analytics support biosimilar development and help meet the FDA’s “totality-of-evidence” expectations.
Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
This week's Chromatography Online highlights include olive waste antioxidant recovery, food and tea analysis, EV isolation, mRNA vaccine purification, perfusion chromatography for oligonucleotides, mass spectrometry in teaching and career advice from “Women in Chromatography.”
Kinjal Bhatt and Ina Varfaj call AI a chromatography equalizer only if training and access keep pace, framing the risk as implementation, not technology.
Gas chromatography–mass spectrometry (GC–MS) and liquid chromatography–mass spectrometry (LC–MS) reveal lasting brain cholesterol loss after myelin damage.
Kinjal Bhatt would expose early-career scientists to the field sooner, while Ina Varfaj says a broken chromatography column taught her failure is normal.
