Christison T, Wang J, Lopez L, Tautenhaun R, and Peake D. ASMS 2016 Poster Previous results demonstrated that ion chromatography (IC) had superior sensitivity and separation over other liquid chromatography methods for small polar metabolites when coupled to a high resolution accurate (HRAM) mass spectrometer using Thermo Scientific™ Orbitrap™ technology mass spectrometers.1 Over 1028 features were found in the food samples, of which ~180 small polar compounds were identified using IC-HRAM. The food samples were complex with complex matrices, however the samples had significant differences. Many of these compounds are also TCA metabolites. Only a small portion of the results are shown. The data was analyzed with Thermo Scientific data analysis tools.
