Abstract
A charge integration baseline compensation method has been established and applied to the design of the spectroscopy amplifier, and the peak drifts of spectrums due to the change of count rates are efficiently decreased. In the application of X fluorescence analysis, the drifts of the peak of silver are reduced to the range less than 0.1 % while the throughput rates of the system are increased from 2 000 s -1 to 12 000 s -1.
