In parallel, an LC-Orbitrap MS platform was used to verify the efficiency of the method as well as a tool to increase the identification confidence of the proposed markers. Based on the results, with FIA-MRMS, comparable and improved projection and prediction models were generated in comparison to those of the more established LC-MS methodology.

2017-03-01 · Recent advances in LC-MS determination of polyphenols in food are presented. • Sample treatment, separation, ionization and MS detection are addressed. • HRMS relevant applications on polyphenols with Orbitrap and TOF are reviewed.

Orbitrap-based mass spectrometers are used in proteomics and are also used in life science mass spectrometry such as metabolism, metabolomics, environmental, food and safety analysis. Most of them are interfaced to liquid chromatography separations, though they are also used with gas chromatography and ambient ionization methods.

2016 Nov;408(28):7905-7915. doi: 10.1007/s00216-016-9919-8. Thermo Scientific™ Orbitrap™ mass spectrometer technology is disrupting the use of mass spectrometry (MS) for qualitative, and more importantly for quantitative analyses, in applied markets. Why is this occurring? For many years, liquid chromatography-triple quadrupole mass spectrometry (LC-QQQ MS) QTOF with a good LC costs similar to Q Exactive Focus Orbitrap LC-MS. Both are within our budget.
