    Thermo Fisher ltq orbitrap
    Example showing correction of highly pronounced systematic parent ion MME along dimension of scan number parameter. The example is an actual LC-MS/MS analysis on an <t>LTQ</t> <t>Orbitrap</t> instrument that is out of calibration with significant sample overloading. Because of sample overloading, the automatic gain control system was not able to properly modulate the ion population within the Orbitrap cell, resulting in space charge effects causing noticeable systematic MME. However, after applying the DtaRefinery and subtracting the systematic MME components predicted by the regression models trained in the space of all four parameters (scan number, m / z , log 10 of ion intensity, and TIC), the mean of the MME distribution shifts from −16 ppm to approximately 0 ppm, and the standard deviation contracts from 4.3 to 0.8 ppm (data not shown). A , the individual parent ion MME plotted as a function of scan number ( blue circles ). B , smoothing the MME residuals with Tukey's running median ( yellow circles ). C , fitting a spline function into smoothed data to have a continuous function for prediction of systematic MME ( red line ). D , corrected parent ion MME by subtracting the systematic MME predicted by the model trained using only the scan number parameter.

Fractions collected were analyzed on analyzed on LTQ-OrbitrapVelos and LTQ-Orbitrap Elite mass spectrometer. Mascot and SEQUEST algorithms were used to perform database searches.

    Article Snippet: In this study, a total of 58 LC–MS/MS runs, of which, 24 bRPLC fractions were performed on LTQ-Orbitrap Elite (Thermo Scientific, USA) mass spectrometer interfaced with Easy- nano LC II nano flow liquid chromatography system (Thermo Scientific), while the remaining 34 fractions (including in-gel and off-gel fractions) were analyzed on LTQ-OrbitrapVelos mass spectrometer interfaced with Proxeon Easy nLC system (Thermo Scientific, Bremen, Germany).
