A method for matching one or more channels to a reference channel in a multiple-channel detector having a digital output, the method including: receiving an analog-to-digital unit (ADU) input value from the multiple-channel detector for each channel; and replacing the ADU input value by an output value corresponding to each channel from a look up table (LUT); wherein the LUT is created by: taking a relative intensity ratio of signals from each channel compared to the reference channel over a range of voltage values; calculating a signal value on the detector that generates a specific ADU value across the entire ADU range of the detector; interpolating the relative intensity ratios to obtain ratios corresponding to the calculated signal values for each channel; and dividing the each of the specific ADU value by the corresponding interpolated ratio to obtain the corresponding output value for each channel. |
