The Rising Role of Foodomics

Ten years since its official definition, foodomics continues to expand the scientific knowledge of food and nutrition while resolving many analytical challenges along the way. LCGC Europe spoke to Alejandro Cifuentes from the Institute of Food Science Research, in Madrid, Spain, about his current foodomics research projects, the overall state of the field, and the future of foodomics.

The Quest for Greener Sample Preparation in Food Analysis

When analytical chemists apply green chemistry approaches, which seek to minimize negative environmental effects, an important area of focus is reducing the consumption of toxic solvents, such as those used in extraction steps in sample preparation. Developing and testing greener extraction processes for food analysis is a major focus of Elena Ibá?ez, a research professor at the Institute of Food Science Research (CIAL-CSIC) in Madrid, Spain.

Thinking Small

By Kate Jones

Pascal Cardinael and Valérie Agasse from the University of Rouen, in Mont?Saint-Aignan, France, reveal the rationale behind miniaturization and the latest developments in miniaturized gas chromatography (GC).

GC×GC–TOF-MS and Comprehensive Fingerprinting of Volatiles in Food: Capturing the Signature of Quality

By Federico Stilo, Erica Liberto, Carlo Bicchi, Stephen E. Reichenbach, Chiara Cordero

Chemical fingerprinting can provide evidence for quality differences resulting from botanical and geographical origins of primary food ingredients, post-harvest practices, production processes (such as traditional versus industrial processes), and the shelf-life evolution of finished products. This article discusses the strategic role and potential of comprehensive two-dimensional gas chromatography (GC×GC) combined with time-of-flight mass spectrometry (TOF-MS) and pattern recognition using template matching for data processing to unravel the quality traits of high-quality food products. Practical examples dealing with high-quality cocoa and extra-virgin olive oil are described.

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

Modern Sample Preparation Methods for Food and Environmental Laboratories

By Jenny Cybulski

Traditional sample preparation method development can often be laborious and costly. Understanding the underlying concepts of the technique can help food and environmental laboratories develop methods in notoriously complex matrices, faster, more efficiently, and provide better chromatography. With the presence of many unique matrices and analytes, methods such as QuEChERS, supported liquid extraction (SLE), or solid-phase extraction (SPE) provide the necessary adaptability for many types of extractions. With customizable methods to work with unique matrices and with the addition of automation, extractions can be improved to save time and provide consistent recoveries.

The LCGC Blog: Emerging and Future Growth Concepts at the Interface between Analytical Chemistry and Medicine

By Kevin A. Schug

Recently, I was honored to attend the 2019 Shimadzu Global Innovation Summit, hosted by Shimadzu Corporation in Kyoto, Japan. The focus of this meeting was to highlight innovation at the interface between analytical chemistry and medicine.

The LCGC Blog: Is Hydrogen the Only Viable Gas Chromatography Carrier Gas for the Long-Term?

By Tony Taylor

As I receive reports from clients in Europe and the United States that helium prices are once again increasing, and warnings are being given regarding yet another laboratory-grade helium shortage, my thoughts turn once again to the use of hydrogen as an alternative carrier-gas for gas chromatography.

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.
