Unusual Applications of Kendrick Plots: Recalibration and Tolerance

Kendrick plots offer an alternative visualization of mass spectral data which reveals ion series and patterning by turn- ing a mass spectrum into a map, plotting the fractional mass (wrongly called mass defect) as a function of mass-to-charge ratios and ion abundances. Although routinely used for po...

Summary:Kendrick plots offer an alternative visualization of mass spectral data which reveals ion series and patterning by turn- ing a mass spectrum into a map, plotting the fractional mass (wrongly called mass defect) as a function of mass-to-charge ratios and ion abundances. Although routinely used for polymer mass spectrometry, two unreported applications of these Kendrick plots are proposed using the program “kendo2”: the graphical recalibration of a mass spectrum via the simulation of a theoretical fractional mass and a multi-segment fit; and the rapid evaluation of scan-to-scan variation of accurate mass measurements used as tolerances for the blank subtraction of UPLC-MS data files. Both applications are compatible with any type of high-resolution MS data including LC/GC-MS(/MS). KCI Citation Count: 0
