2021/5/4 · The general shift to comprehensive two-dimensional gas chromatography (GC×GC) happened because of the superior peak capacity, sensitivity, and selectivity of GC×GC (9). In addition, GC×GC instrumentation allows more effective management of the large dynamic range encountered in decomposition VOC studies (9).

2020/7/1 · Correlation of free SO 2 values measured by the headspace gas detection tube (HS-GDT) and headspace gas chromatography (HS-GC) methods. Since partitioning of SO 2 in the headspace is governed by Henry’s Law, effort was made to ensure that analysis of wines by the HS-GC and HS-GDT methods was performed at the same temperature ± 1°C.
In this study, an approach employing headspace sampling (solid‐phase microextraction) with comprehensive two‐dimensional gas chromatography coupled to high‐resolution‐time‐of‐flight

Waste materials (solid and liquid wastes) from oil and gas development may pose risks to water quality and environmental health. Exposure pathways include land application, breaching of surface impoundments and pipelines, discharge of treated wastewaters and sludge, failures in well completions through shallow aquifers, and/or migration through fracture networks to adjoining permeable formations.
This method employs the full evaporation technique via a static headspace sampler, followed by gas chromatography–mass spectrometry (SHS-GC/MS/MS). In the validation process, spiked terpenoids were quantified with acceptable repeatability, reproducibility, sensitivity, and accuracy.
Aijiren's gas chromatography (GC) systems combine innovative technology, Instrument Intelligence, and expected reliability to offer the broadest range of GC solutions. Integrated Instrument Intelligence provides labs and operators wth predictive technologies to help avoid common GC problems before it affects chromatographic accuracy.
