Abstract
In a background compensation in material analysis, the value of the background signal is separated from the value of a gross analyte signal generated by athermal radiation excitation after thermal excitation. The thermal atomization takes place in a stepwise manner by stepwise heating and each step is divided into a first part for the measurement of the gross analyte signal and a second part for the measurement of the background signal.
