Front. Public Health 8:558226. doi: 10.3389/fpubh.2020.558226 2011-04-01 Furthermore, we found that the Orbitrap analyzer, rather than the analytical column, was easily saturated with higher loading amount, thus limited the dynamic range of MS1‐based quantification. By using optimized parameters, 10 000 proteins and 110 000 unique peptides were identified by using 20 h of effective liquid chromatography (LC) gradient time.

Ions entering the Orbitrap are captured through "electrodynamic squeezing," after which they oscillate around the central electrode and in between the two outer electrodes.

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. Cite.
