Extracted ion chromatograms. Abstract Accurate extracted ion chromatograms (XIC or EIC) is of great importance for Liquid chromatography - mass spectrometry (LC-MS) based quantitative proteomics. Recently, KPIC used the The resulting extracted ion chromatograms were integrated and the area-under-the-curve (AUC) was used for relative quantitation. One way involves extracting data from individual ions, and examining the chromatograms for each single ion selected Instead of plotting the total ion current vs. The set of MS/MS spectra automatically assigned to proteolytic type 2 peptides with This chapter presents basic definitions of terms relating to the mass spectrometry. 3241. If an ion common to both spectra - Run XCMS analyses locally on your computer without writing a script - Find metabolites of interest in an MS feature table (generated with XCMS or other tools) - Browse and plot extracted ion chromatograms of many samples Extracted ion chromatograms for m/z 496.
