Abstract
PURPOSE:To improve measurement accuracy and reproducibility by detecting the rise of sample peak with the smoothed photo detector output and holding the same as a base line. CONSTITUTION:A peak catch part 3 consisting of first, second auto response circuits T1, T2, a trough bottom detecting circuit BOT and a subtraction circuit Su is provided between an absorptivity converter 5 and a signal processing part 4 and display part 6. Then, the light from a hollow cathode lamp HCL having passed through the through-hole of a sample atomization part A is divided with a spectroscope D, after which it is converted to an electric signal with a photo detector 1 and to an absorptivity signal with an absorptivity converter 5. After this signal is smoothed, it is detected of the rise of the sample peak and the signal level of that time is held as a base line and is substrated from the raw signal raw signal which in turn becomes the profile signal of the sample peak. In a signal processing part 4, the rise, area, etc. of the peak are obtained and are displayed in a display part 6.
