This study shows the analysis of several commercially available coconut water products using a GC/MS system equipped with a versatile autosampler and sample preparation robot capable of performing a wide range of standard sample introduction techniques including thermal desorption.

This application note describes two automated methods for screening of extractable compounds from materials for food packaging, medical or technical purposes. The first method is based on automated liquid extraction performed by the GERSTEL MultiPurpose Sampler (MPS),...

In this study, a method was developed for quantitative determination of seven phenolic compounds in scotch whisky. Two different whisky brands were analyzed by Stir Bar Sorptive Extraction (SBSE), based on novel EG-Silicone Twisters, combined with thermal desorption-gas chromatography-mass spectrometry (TDGC- MS).

This study shows the analysis of a commercially available personal care product using the GERSTEL MultiPurpose Sampler (MPS) configured with Thermal Desorption Unit (TDU), Cooled Injection System (CIS) PTV-type inlet, Dynamic Headspace (DHS) and pyrolysis (PYRO) modules...

This paper describes an automated pyrolysis system for gas chromatography (GC) based on a filament type pyrolyzer combined with a commercially available thermal desorption instrument, onto which the pyrolysis module is installed.

A method for the determination of trace amounts of off-flavor compounds such as 2-methyl isoborneol (MIB), geosmin and 2,4,6-trichloroanisole (TCA) in drinking water is described based on dynamic headspace coupled to selectable one-dimensional or two-dimensional gas chromatography - mass spectrometry with...

Stir Bar Sorptive Extraction (SBSE) is an innovative and efficient method [1] for the extraction of drugs and pharmaceuticals from blood-, urine- and tissue samples in a forensic toxicology laboratory. As shown in this application note and earlier publications [2,3,4], SBSE is an effective screening tool for drugs and pharmaceuticals in biological fluids and tissue.

Fruit and vegetable extracts that are produced following the well established QuEChERS method [1,2] typically contain a significant amount of involatile matrix material. After several injections of such extracts into the GC, sufficient matrix residue will be present in the GC inlet liner to lower...

The Deepwater Horizon oil rig explosion and the subsequent massive oil spill is expected to be the worst offshore oil catastrophe in United States history and is now beginning to impact fragile ecosystems, air and water quality, and food supplies.

This method uses a QuEChERS (quick, easy, cheap, effective, rugged, and safe) single-step acetonitrile (ACN) extraction and salting out liquid-liquid partitioning to extract PAHs from seafood tissue. Stir Bar Sorptive Extraction (SBSE) is then used as a combined cleanup and concentration step,...
