A Novel, Selective, and Sensitive Vacuum Ultraviolet Method to Detect Trace and Ultra-Trace Levels of Moisture in Acetonitrile Used in Oligonucleotide Synthesis (Apr 2023)
The power of vacuum ultraviolet (VUV) light absorption can be useful in problematic moisture determination areas. A new detector for gas chromatography (GC) based on VUV absorption can potentially detect ultra-trace levels of moisture in acetonitrile.
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.
