Analysis of Carbohydrates by Ultraperformance Liquid Chromatography and Mass Spectrometry
In this application, simple and complex carbohydrates, which are often analyzed by HILIC, are separated on the BEH Amide column and then directly detected with electrospray ionization mass spectrometry (ESI-MS) with no need for derivatization, post-column addition, or metal complexing agents.
Koji Yamaguchi of the International University of Health and Welfare (Narita, Japan) discusses a novel derivatized liquid chromatography-tandem mass spectrometry (LC-MS/MS) method plus propofol glucuronide (PRG) marker which improves forensic propofol detection.
Gas chromatography-mass spectrometry (GC-MS) coupled with headspace solid-phase microextraction )HS-SPME) links cocoa variety to chocolate aroma and flavor profiles.
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.
