Abstract:
1. A method for decreasing a total settling time of a mass spectrometer (MS) system having at least two stages, comprising: (a) receiving a list of values for parameters for the at least two stages of the MS system, wherein the list contains at least three values for each of the at least two stages, and wherein a first parameter is associated with a setting of a first stage and a second parameter is associated with a setting of a second stage; (b) assessing settling times for the first and second parameters, wherein a settling time of a stage is related to a corresponding parameter delta, wherein the parameter delta is a difference between two sequential vales of the same parameter; (c) changing the order of the list and repeating (b); and (d) performing an MS measurement according to an order of the list for which the total settling time is reduced compared to another order.
