LCGC Interviews

John Hinshaw offers his insights into how the current helium shortage will affect gas chromatographers and answers some concerns of LCGC Europe readers selected from the CHROMmunity.

The HPLC 2012 conference was abuzz with talk of "slip flow" following the talk given by Mary Wirth of Purdue University about her groundbreaking work involving protein column efficiency. In this interview, Wirth explains how “slip flow†works and what this discovery can contribute to the application of LC-MS to disease research.

In a new paper to be published in the July issue of LCGC North America, Fabrice Gritti and Georges Guiochon of the Department of Chemistry at the University of Tennessee (Knoxville, Tennessee) present results from their latest studies in their research on the kinetic mechanisms of chromatography columns packed with core?shell particles.

A retention index tool called iMatch that aims to reduce the number of false positive results when using gas chromatography mass spectrometry (GC-MS ) and comprehensive two-dimensional gas chromatography mass spectrometry (GC×GC-MS) has been developed by a team of researchers from the University of Louisville. Alasdair Matheson, editor of LCGC Europe, spoke to Xiang Zhang to find out more.

High-temperature liquid chromatography (LC) is a hot topic in separation science at the moment. David Collins from the Irish Separation Science Cluster based at Dublin City University, Ireland, describes a new column heater design that aims to enhance the efficiency of high temperature separations.

LCGC recently interviewed Walter J. Krol, Ph.D., of the Connecticut Agricultural Experiment Station (New Haven, Connecticut) about his laboratory?s involvement in analyzing samples from the 2010 Deepwater Horizon oil spill in the Gulf of Mexico using a QuEChERS-based method.
