Which will be better for our task? I am a bit confused. Thermo Orbitrap have the best Resolving power: 70,000 at m/z 200. are benchtop LC-MS systems composed of six unique sections: RF-lens, bent-˚ atapole, hyperbolic quadrupole mass ˜ lter, C-Trap, HCD cell, and the Orbitrap mass analyzer (Figure 2). Detection of N-(1-deoxy-D-fructos-1-yl) fumonisin C1, C2 and C3 (NDfrc-FCs) in a reference material of corn powder were performed with LC-Orbitrap MS. The peaks of NDfrc-FCs were eluted 0.1 ~ 0.3 min earlier than those of fumonisin C1, C2 and C3 (FCs), from the C18 column, probably due to their hydrophilic structures having the carbohydrate residues.

2018-12-01 · The results were confirmed by LC-Orbitrap MS analysis. In addition, the eight glycated sites of R-Oval were identified by the HCD MS/MS, which are located in the hydrophilic region and their adjacent amino acids are hydrophilic amino acids, acidic amino acids or basic amino acids. Determination of Illicit Drugs in the Water Cycle by LC–Orbitrap MS Pim de Voogt Earth Surface Science, Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, Amsterdam, The Netherlands
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. The Orbitrap differs from FTICR-MS by the absence of a magnetic field and hence has a significantly slower decrease of resolving power with increasing m/z.
