I am currently working with targeted, suspected and non-targeted approaches for the analysis (LC- and GC- Orbitrap) of organic micropollutants in the 

In mass spectrometry, Orbitrap is an ion trap mass analyzer consisting of an outer barrel-like electrode and a coaxial inner spindle-like electrode that traps ions in an orbital motion around the spindle. The image current from the trapped ions is detected and converted to a mass spectrum using the Fourier transform of the frequency signal. Thermo Scientific hybrid quadrupole-Orbitrap mass spectrometers enable both targeted and non-targeted screening and characterization. They also work with a broad range of sample type applications so that your laboratory can go from compound discovery to quantitation without relying on different instruments and technologies.

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.

Cerno Y.Wang,D.Kuehl Pittcon 2020. 2010-06-18 · High-resolution mass spectrometry coupled to LC is a very powerful combination. The Orbitrap publications most frequently cite the use of reversed-phase chromatography. The use of ultra-high pressure LC (U-HPLC) in combination with the Orbitrap detection, both for peptide and small molecule analyses is of a particular interest.
