A Comparison of ITEX Dynamic Headspace–GC/MS to other Enrichment Techniques for Analysis of Flavoring Compounds
The automated ITEX Dynamic Headspace unit demonstrated equivalent accuracy and precision when compared to purge and trap and overall was more sensitive than the other enrichment techniques. The ITEX unit allows for automated analysis and optimization of conditions which drastically reduces analyst’s time when compared to performing the experiments manually with the purge and trap without any reduction in sensitivity, accuracy and reproducibility.
Analysis of volatile compounds from honeys to differentiate plant and geographical origins
The analysis of volatile organic compounds (VOCs) is a faster approach to identify the honey’s origin than traditional methods, which is important for the quality control of honeys. In-tube extraction dynamic headspace (ITEX-DHS) is a fully automated microextraction technique, in which the enrichment of analytes takes place by repeated aspiring and dispensing of the sample headspace through a sorbent trap
Analysis of flavors, pesticides, and biomarkers directly from complex food matrix using the automated Vacuum In-Tube Extraction (V-ITEX)
Extraction of volatile compounds is a widely used approach for analysis of foods and beverages. By the nature of gas phase sampling, the limiting factor for polar analytes are given by low vapor pressure or higher boiling points of semi-volatile compounds. These limitations can be overcome by sampling at decreased pressure levels using vacuum conditions. This has been shown in several publications using vacuum sampling techniques. In this study, a fully automated approach of Vacuum In-Tube Extraction (V-ITEX) is presented, a simple and fully automated technique using PAL system autosamplers. The application examples include flavors, fragrances, off-flavors, pesticides and biomarkers by extractions directly from the food sample matrix, such as Honey, Bee Wax, Cheese, Onions, Blood and Urine.

Headspace Analysis: Reproducibility of Syringe Headspace Injections for Aqueous Samples
This article describes the optimization of residual solvents analysis according USP <467> and Ph.Eur. 2.4.24 using the automated syringe headspace technique on GC-FID and GC-MS systems. The precision of analysis ranged from 4.3 to 7.8 % RSD (GC-FID) for class 2 solvents for all analytes investigated in this study. These values fully comply with USP <467> and Ph. Eur. 2.4.24 requirements.
Quantitation of volatile organic compounds in drinking water using ITEX
Demonstration of a routine analytical method for the quantitation of volatile organic compounds in drinking water, using the
TriPlus RSH ITEX system along with a Thermo Scientific™ ISQ™ 7000 MS system coupled with a Thermo Scientific™ TRACE™
1310 Gas Chromatograph (GC) and Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS). Method linearity
and detection limits were assessed to evaluate method performance.
