Featured LCGC Interviews

The Benefits of AQbD

The benefits of an analytical quality by design (AQbD) approach to method development cannot be underestimated. The Column spoke to Changqin Hu and Xia Zhang from the National Institutes for Food Drug Control, in Beijing, China, about their work developing a dual-gradient elution stability-indicating method for cloxacillin within an AQbD framework.

Rapid Trace Analysis of Multiresidue Contaminants

Mira Petrovic from the Catalan Institute for Water Research (ICRA) in Girona, Spain, reveals the advantages and practical applications of a novel method she developed for the multiresidue trace analysis of pharmaceutical compounds and their corresponding metabolites and transformation products using dual-column liquid chromatography (LC) coupled to tandem mass spectrometry (MS/MS).

The LCGC Blog: Potential for Use of Stable Isotope–Labelled Internal Standards in Gas Chromatography–Vacuum Ultraviolet Spectroscopy Methods

By Kevin A. Schug

Evaluating the ability of gas chromatography–vacuum ultraviolet detection (GC–VUV) to distinguish and correctly identify various isomer and isotopologue forms of an analyte through the lens of spectral similarity.

Sampling Volatiles From Fragranced Consumer Products Using High-Capacity Sorptive Extraction

By Lara Kelly, David Barden

This study describes the analysis of fragranced washing detergent and washing powder using probe-based headspace and immersive sorptive extraction, in conjunction with analysis by thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS). As well as discussing the differences between the two samples, the analyte ranges covered by headspace and immersive sampling are compared.

Mass Spectrometry

Headspace Solid-Phase Microextraction Coupled with Gas Chromatography–Mass Spectrometry for the Characterization of Polymeric Materials

By Peter Kusch

HS-SPME-GC–MS is a valuable technique for identifying volatile organic compounds, additives, and degradation products in industrial rubber, car labeling reflection foil, and bone cement materials.

Recent Advances in Comprehensive Chromatographic Analysis of Emerging Drugs

By Ira S. Lurie, Lauriane Tremeau-Cayel, Walter F. Rowe

To address the challenges of analyzing new illicit drugs, emerging techniques such as UHPSFC with MS and UV detection, and GC with VUV detection, may be needed, particularly for distinguishing positional isomers and diastereomers.

Sample Preparation

Analysis and Fate of Surfactants in the Aquatic Environment

By LCGC Editors

According to Analysis and Fate of Surfactants in the Aquatic Environment (Volume 40 of Wilson & Wilson's Comprehensive Analytical Chemistry), an understanding of the fate and behaviour of organic chemicals, such as surfactants?

The LCGC Blog: Screening Platforms for HPLC Method Development

By Tony Taylor

I'm often asked to help with the development of column "screening" platforms and automated development systems. While this covers a large amount of analytical science there are some common elements to this type of approach, perhaps the most important of which is column selection. Unsurprising given that "selectivity" is the most powerful tool we have in chromatography and we all know that the best way to optimize selectivity is to choose the most appropriate stationary phase.

The LCGC Blog: Break Out the New Research Results for the New Conference Season

By Kevin A. Schug

I 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.

HPLC Mobile Phases – 10 bad habits to avoid

The 10 bad habits to avoid when producing HPLC mobile phases.

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.
