Comparative Analysis of Lipophilic Wood Extractives by GCxGC-TOFMS for Enhanced Chromatographic Resolution and Compound Identification
6 Apr 2011Read this application note to learn about the enhanced detection and increased peak capacity available with GCxGC-TOFMS for complex lipophilic wood extractives. The comprehensive two-dimensional chromatography resolves analytes that would otherwise totally co-elute and be buried by high concentration analytes in one-dimensional chromatography. It further illustrates deconvolution of fast acquisition non-skewed time-of-flight mass spectrometry (TOFMS) spectra for closely eluting analytes of similar chemical structure. Soxhlet extractions are compared using different solvents to maximize and isolate the detection of possible volatile components in wood by GCxGC-TOFMS.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.

Tandem mass analyzers such as TOF/TOF systems can be used to increase resolution and sensitivity of your analysis.

Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
