LCGC TV: Richard Henry on Optimizing UHPLC Methods
Ultrahigh-performance liquid chromatography (UHPLC) offers improved run-times and enhanced resolution when compared with conventional liquid chromatography (LC) methods. In this new video from LCGC TV, Richard Henry, a consultant from State College (Pennsylvania, USA), gives his advice on how to select UHPLC column size and discusses the features of an optimal UHPLC instrument.
Kirstine Nielsen of Aarhus University (Denmark) discusses how targeted metabolomics ratios helped build a robust bloodstain time-since-deposition tool.
Gérard Hopfgartner explains how atmospheric pressure photoionization can generate radical cations in LC–MS, unlocking EI-style spectra and NIST's spectral library.
LCGC International spoke to Akina Nara of Japan’s Tohoku Medical and Pharmaceutical University about a new study which links a blood compound to how long a body has been dead.
A method coupling gas chromatography-tandem mass spectrometry (GC-MS/MS) and multiple reaction monitoring (MRM) tracks lipid markers of decomposition in commingled remains.
This week's top stories on the Chromatography Online website spotlight LCGC International's new SFC-focused interview series charting the technique's rise alongside LC and GC, complemented by a practical GC data-reporting refresher and a study using chromatography to detect trace pesticides in tap water.
