March 28th 2024
At the 2024 Pittcon Conference, Elizabeth Humston-Fulmer of LECO Corporation presented an improved workflow which uses two-dimensional gas chromatography (GCxGC) with dual time of flight (TOF) MS/FID detection. Shortly after Pittcon, Humston-Fulmer discussed this analytical method with us.
Pittcon 2024: Identifying PFAS in Anti-Fog Products Using GC-TOFMS
February 25th 2024During a workshop at Pittcon, David Alonso of LECO Corporation discussed how gas chromatography–time-of-flight mass spectrometry (GC-TOFMS) can be used to identify polyfluorinated alkyl chemicals (PFAS) chemicals in anti-fog product solutions.

Are You Ready to Switch to Comprehensive Two-Dimensional Gas Chromatography?
September 1st 2023Comprehensive two-dimensional GC×GC has made great strides in the past 20 years. The author discusses advances in instrumentation, column sets, data analysis, and the range and types of samples amenable to this method.
Analyzing Extractables in Pharmaceutical Packaging Material with 2D-GC-TOF-(MS)
August 26th 2023As part of the upcoming Recent Advances in Gas Chromatography meeting, Nicholas Morley will look at how two-dimensional gas chromatography-time-of-flight-mass spectrometry analyzes pharmaceutical packaging.
GCxGC/TOF-MS and GC-TOF-MS Comparisons To Be Made at Science and Industry Museum
August 26th 2023Two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC/TOF-MS) and gas chromatography–time-of-flight mass spectrometry (GC-TOF-MS), two different gas chromatography techniques, will have their procedures and uses compared at the Science and Industry Museum, in Manchester, UK.
A Modern Mineral Oil Hydrocarbon Analysis
August 1st 2023Giorgia Purcaro of the University of Liège discusses the advantages offered by the liquid chromatography–comprehensive multidimensional gas chromatography time-of-flight mass spectrometer/flame ionization detector (LC–GCxGC–TOF-MS/FID) method in the analysis of mineral oil.
GC✕GC–TOF-MS Helps Quantify Pesticides in Water Susceptible to Contamination
April 28th 2023Pesticides in local surface and groundwaters were purified and enriched with solid-phase extraction, then analyzed using multidimensional gas chromatography coupled to mass spectrometry, with the results compared to those found by gas chromatography–quadrupole mass spectrometry.
The LCGC Blog: GC×GC…Why Bother?
January 3rd 2023Comprehensive two-dimensional gas chromatography (GC×GC) is becoming increasingly popular, but is still not used as commonly as it could be. That likely means that the technique is still not widely understood. This article is intended to begin demystifying GC×GC by presenting a simple explanation of how it works and its major benefits.
Separation Science: The State of the Art: Multidimensional Gas Chromatography Moves Forward
December 1st 2022In this extended special feature to celebrate the 35th anniversary edition of LCGC Europe, key opinion leaders from the separation science community explore contemporary trends in separation science and identify possible future developments.
