Screening for Melamine Adulteration in Protein-Based Foods by GC/MS
15 Jul 2009: Melamine is a nitrogen-rich industrial chemical with many different uses; one of the most common is in the manufacturing of melamine resin, a very durable polymer. This paper presents a robust, efficient and definitive analysis of melamine and related analogues. The sample preparation, including extraction and derivatization, are discussed in addition to the optimized gas chromatography/mass spectrometry (GC/MS) method.

The Application of GC/MS to the Analysis of Pesticides in Foodstuffs
15 Jul 2009: Pesticide contamination of foodstuffs has become a worldwide concern, prompting various levels of regulation and monitoring. This paper outlines a GC/MS method, allowing for the quantification of low-level pesticides with SIM, while simultaneously performing quantification of higher concentrations using full-scan acquisition (SIFI™ - single ion and full ion scanning).

The Determination of 2,4,6-Trichloroanisole in Wine using Headspace Trap with GC/MS
15 Jul 2009: 2,4,6-trichloroanisole (TCA) is found in the cork used to seal glass wine bottles. The determination of TCA in wine is necessary due to the extremely low level of sensory perception for this compound. Wineries require a fast, reliable technique that can produce accurate and precise results for TCA analysis.

Applying the Technology of the TurboMatrix 650 ATD to the Analysis of Liquid Accelerants in Arson Investigation
15 Jun 2009: As with all forensic analyses, the data generated in arson investigation must be legally defensible, creating the need for duplicate analyses and sample archival. This study discusses how the use of solvents for sample preparation can be eliminated and how sample recollection can be implemented on the TurboMatrix™ 650 ATD, using thermal extraction combined with dynamic headspace and automated thermal desorption.
