Triazine herbicides are commonly used in crop management to remove invasive plant species. These herbicides disrupt the photosynthesis cycle, leading to plant death and can contaminate soil and groundwater if used in high enough concentrations and for long enough duration. As such, the monitoring of these herbicides is important to minimize and monitor contamination. The app note outlines using a systematic screening protocol to develop a method for the analysis of a mixture of seven structurally similar triazine herbicides.
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.
