The KMDNoise method is based on the observation that the CH2 based KMD values of noise and analyte masses are naturally separated in a KMD plot, allowing the function to select a region with only noise to calculate the average intensity. We refer to this as the KMD slice method. In princi...
(in this case CH2) by an integer that is experimentally determined to accomplish the desired separation. This value is then used in the typical KM and KMD calculation in order to calculate the “resolution enhanced” KMD (re-KMD). For example, the integer 21 is used to adjust the CH2 ...
