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.

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.

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.

Sample preparation is a crucial part of the analysis of foodstuffs. Current sample preparation techniques used in food analysis are reviewed and the advantages and drawbacks of each one are discussed.

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.

Shimadzu Application Note

Using narrow-bore column fast GC combined with rapid scanning qMS to analyse flavours and fragrances is described.
