Two-dimensional GC×GC platform in combination with FID detection and High Resolution Mass Spectrometry
SRA Instruments developed configuration and analytical methodology to match the challenging qualitative and quantitative needs of MOSH/MOAH analysis. The solution is based on a two-dimensional GC×GC platform in combination with FID detection and High Resolution Mass Spectrometry. This technique significantly increases the capacity to characterize the two fractions preliminarily separated by HPLC thanks to its superior chromatographic resolution, offering a more detailed classification of the hydrocarbon profiles.
Zoex thermal loop modulator with close-cycle refrigeration (no liquid nitrogen needed) grants excellent chromatographic performance combined to high flexibility, hereby assisted by SRA Optimode, developed to fully benefit from potential of thermal modulation while optimizing resources. Parallel FID/QTOF detection allows reducing samples/solvents’ amounts and analysis times to enhance throughput.
The solution developed by SRA Instruments combines performance with flexibility and can act as a powerful analytical tool – complementary to the traditional LC-GC-FID methodology – for more insightful, confirmatory investigation of samples found positive to contamination.
