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.

Over the last 30 years, the occurrence of head and neck cancer in Spain has been increasing, and now accounts for between 5–10% of malignant tumours diagnosed each year.1 In a new study published in the journal Chromatographia, solid-phase microextraction (SPME) with gas chromatography coupled to mass spectrometry (GC–MS) has been performed to identify two potential biomarkers of epidermoid laryngeal cancer, that could be used in non-invasive diagnostic testing.

This article presents a new method to evaluate the temperature shift observed in analytical temperature rising elution fractionation (ATREF). The evaluation is based on the dependence of the measured peak temperature as a function of heating rates. Application of the proposed method does not require any knowledge of the fluid circuit characteristics geometry and avoids the use of narrow preparative TREF standards. The results are found to be more accurate than the method that is usually applied.
