摘要：

Background correction in atomic absorption spectrometry using high-speed electronic circuitry has been developed. Electrical responses are generated from two light sources; an atomic spectral lamp and a modified Beckman hydrogen arc lamp. Repetition rate of the pulses (2. 6 msec) was limited by the increasing distortion of the pulse shape. Instantaneous relationships between the various electronic components was established using a synchronizing pulse generator.
