Make Your Unknowns, “Known” with High Resolution Mass Spectrometry

The Application Notebook - Jun 01, 2015

The combination of high performance mass spectrometry and comprehensive two-dimensional GC definitively takes unknown components and unambiguously identifies an important odor component in a perfume sample.

Comparison of Edible Oils by GCxGC–TOF-MS and GC–High Resolution TOF-MS for Determination of Food Fraud: A "Foodomics" Approach

Special Issues - Mar 01, 2014

Here, a method to characterize edible oils and edible oil mixtures through fingerprinting and the isolation of individual analyte differences is reported. Aroma and flavor analytes in extra virgin olive, olive, peanut, grapeseed, and vegetable oils were sampled with headspace solid-phase microextraction (HS-SPME).

Analysis of Multiple Classes of Cigarette Smoke Constituents by GCxGC-TOFMS

The Application Notebook - Feb 01, 2012

GCxGC-TOFMS provided a comprehensive analysis of tobacco smoke. Individual smoke constituents across several target compound classes were extracted, chromatographically resolved, then identified and quantified with mass spectral detection.
