Abstract

A method for processing an image charge / current signal representative of one or more ions undergoing oscillatory motion within an ion analyzer, the method comprising obtaining a recording of the image charge / current signal generated by the ion analyzer in the time domain, the method further comprising: obtaining, by a signal processing unit, N distinct values ​​(OP n , where n=1 to N, N≧M) from a plurality of spectral peaks including harmonic peaks associated with the ions of interest. nm is the coefficient, TP m The simultaneous equations with [0052] TIFF2024523214000055.tif22138 The charge of the ion of interest is calculated by solving the correction value (TP m ) based on its size.
