Scientists at the University of Cambridge (Cambridge, UK) have reconstructed the early conditions of the Earth?s oceans to find that spontaneous chemical reactions could have generated the first biological molecules, before the evolution of organisms or the existence of enzymes.1 The study published in the journal Molecular Systems Biology presents data collected from liquid chromatography?triple quadrupole mass spectrometry (LC–QTOF–MS) suggesting that reactions central to our core metabolism could have spontaneously occurred.
Analysis of PFAS in Milk by LC-MS/MS
May 15th 2025Dairy milk is one commodity that can be impacted by environmental contaminants, such as PFAS, so it is important to implement extensive, robust, and accurate testing. In this work, a sensitive and reliable method was developed for the analysis of PFAS in milk by LC-MS/MS at levels as low as 0.01 µg/kg.
