Advances in LC–MS for Food Analysis

May 1, 2012

In this review, the most recent LC–MS approaches are discussed, as well as the technical requirements for linking an LC system to a mass spectrometer. The advantages of on-line 2DLC in the "comprehensive" mode are also illustrated and selected applications for the analysis of common foodstuffs, such as triacylglycerols, carotenoids and polyphenols, are described. Finally, future trends for LC–MS in food analysis are reported.

Advances in GC–MS for Food Analysis

May 1, 2012

An overview of important GC–MS techniques currently used in food analysis is described. Considerable attention is devoted to the use of the mass spectrometer, in relation to its poptential for separation and identification. The importance of comprehensive GC?GC is also discussed.

Advances in Multidimensional LC–GC for Food Analysis

May 1, 2012

On-line heart-cut LC–GC and, more recently, comprehensive LC–GC (LC?GC) are very powerful analytical techniques because of the combination of the selectivity features of LC with the high efficiency of GC. This article presents an overview of the most recently used interfacing systems, as well as applications in the food analysis.

Static Headspace GC–MS Detection of Residual Solvents—A Possible Simultaneous Identification and Quantitation Method

January 1, 2012

A new procedure is proposed that provides identity parameters for headspace-applicable residual solvent Class 1 and Class 2 compounds addressed in the current US Pharmacopeia <467> method.

The Potential of Polymeric Monolithic Capillary Columns for the LC–MS Analysis of Intact Proteins

January 1, 2012

Describes the preparation of a reversed-phase monolithic column with an optimized porous structure to separate intact proteins using LC–MS.

Ultratrace Quantitative Analysis of Catalyst Poisoners using a Dedicated GC–MS Analyser

April 1, 2012

A GC–MS analyser is described that is reported to substantially expand the workable application range of a classic catalyst contaminants analyser. The use of FS/SIM mode permits identification of unknown contaminants in combination with reliable quantification at trace and ultratrace amounts.

The Potential of Polymer Monolithic Capillary Columns for the LC–MS Analysis of Intact Proteins

March 1, 2012

Describes the preparation of a reversed-phase monolithic column with an optimized porous structure to separate intact proteins using LC–MS.

Rapid Multidimensional Liquid–Gas Chromatography for the Analysis of Saturated Hydrocarbon Contamination in Foods containing Vegetable Oil

January 1, 2012

A fast heart-cutting liquid chromatography–gas chromatography (LC–GC) method for the analysis of mineral oil saturated hydrocarbons (MOSHs) in a range of widely consumed foods is described.

Asymmetrical Flow Field Flow Fractionation for Investigating Intermolecular Interactions of Multifunctional Polymers

December 1, 2011

Describes how asymmetrical flow field flow fractionation (AF4) can be used to characterize intermolecular interactions in multifunctional polymers used in drug delivery.
