Featured LCGC Interviews

The Art of Museum Conservation Using Solid-Phase Microextraction–Gas Chromatography–Mass Spectrometry

The Column spoke to Katherine Curran, a lecturer in Sustainable Heritage at the UCL Institute for Sustainable Heritage in London, UK, about her work classifying museum artefacts using volatile organic compound (VOC) analysis and solid-phase microextraction–gas chromatography–mass spectrometry (SPME–GC–MS).

Evaluating Marine Algae for Therapeutic Effects

Snezana Agatonovic-Kustrin, a professor in pharmaceutical chemistry at Monash University, in Kuala Lumpur, Malaysia, spoke to The Column about the development of a method to evaluate antidiabetic and antioxidant activity in marine algae using high-performance thin-layer chromatography (HPTLC)-direct bioautography.

Injecting Water onto a GC Column: Solving the Mystery of Poor Chromatography

By Chris English

Ethylene glycol is a particularly difficult compound to analyze because it is not easily extracted from water. Many environmental samples originate from water runoff at airports, where ethylene glycol is used as a de‑icing agent for airplanes during winter months. Hydraulic fracturing is a technique where pressurized fluid and sand or other solids (proppant) are used in gas drilling to allow gas extraction. Glycols are a common ingredient in most hydraulic fracturing fluid and play a key role in preventing emulsifications and stabilizing the solutions. The direct aqueous injection of ethylene glycol is challenging because it can be difficult to attain reproducibility and good peak shape. The large expansion volume of water can cause backflash, carryover can cause inconsistent results, and excess water can extinguish the flame ionization detection (FID) flame. This article describes a robust approach to analyze glycols in aqueous samples, which reduces downtime and maintains sensitivity.

10 Ways to Break Your LC-MS

If there’s one mantra that’s essential for an LC (or GC)-MS operator it’s “contamination, contamination, contamination”. Keep contamination to a minimum and you’ll enjoy a reliable instrument; don’t take the necessary precautions and instead you’ll enjoy reaching for the vent switch and purchasing lots of spares.
