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.

A single-sample workflow for joint metabolomic and proteomic analysis ofclinical specimens

Integrating proteomic and metabolomic data enhances ourunderstanding of biological processes and diseasemechanisms. Traditional multi-omics workflows often requireseparate sample processing, leading to increased variability.To address this, we developed MTBE-SP3, an optimizedsingle-sample workflow that combines a 75% EtOH/MTBEmetabolite extraction with automated single-pot solid-phase-enhanced sample preparation for proteins.

Advantages of automated and miniaturized µSPE clean-up in pesticides residues analysis

Recent developments in pesticides analysis extend the well-established methods to higher productivity and reliability while minimizing consumption and exposition to harmful chemicals. A workflow was developed that allows automatic preparation of calibration standards, automatic sample dilution, and automatic clean-up of sample extracts on one instrument, showing that miniaturized automated solutions are reducing errors, improving analytical consistency and protecting the environment in one convenient approach.

Analysis of flavors, pesticides, and biomarkers directly from complex food matrix using the automated Vacuum In-Tube Extraction (V-ITEX)

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.
