The LCGC Blog: Break Out the New Research Results for the New Conference Season
January 30th 2018I always think of a conference presentation to be like a rock band concert. Sure, the band is going to play some of their biggest hits, but they also want to propagate their new stuff. More importantly, they want to put on a show so that people are entertained. I do think there should be more emphasis on entertaining the audience during oral presentations.
Combatting Antimicrobial Resistance Through VOC Analysis of RTIs
January 16th 2018Researchers from the Liverpool School of Tropical Medicine and the University of Warwick have conducted a pilot study to assess the viability of a GC–IMS for the analysis of volatile organic compounds (VOCs) in exhaled breath for the diagnosis of bacterial respiratory tract infections (RTIs) in hospital patients.
Novel Pesticide Extraction Method for River Water Samples
January 12th 2018Researchers from the Harbin Institute of Technology, Harbin, China, have developed a simple method for the extraction of organochlorine pesticides (OCPs) from river water samples using magnetoliposomes as adsorbents and gas chromatography tandem mass spectrometry (GC–MS/MS).

The LCGC Blog: Three Peaks Shapes You Really Don’t Want to See in Your Gas Chromatogram
January 9th 2018Sometimes troubleshooting a separation can rely upon the end user spotting subtle clues within the chromatogram, and at other times the visual signs can be much more obvious. To start the New Year, I wanted to share some of the most common issues that we see with peak shapes in gas chromatography in the hope that if you spot some of these in your own work, you may be able to intercept problems and deal with them more effectively.
Analyte Derivatization as an Important Tool for Sample Preparation
January 1st 2018During the developmental stages of chromatography, the use of sample derivatization was prevalent either to render difficult-to-separate analytes ready for chromatography or to improve analyte detectability. As chromatography techniques advanced, including detection, the need for derivatization was less pronounced. Today, there is a resurgence of interest in derivatization schemes; however, the new generation of separation scientists is not as well-versed in these reactions. Some of this resurgence is for newer purposes, such as combining two or more derivatizations for the analysis of multiple compound classes, or to develop greener approaches. In this month’s instalment, we explain the use of chemical derivatization in the separation sciences, generally, and in sample preparation specifically.
