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.
