Title:
SPECTROSCOPIC ANALYSIS APPARATUS
Document Type and Number:
Japanese Patent JPS59120844
Kind Code:
A
Abstract:

PURPOSE: To automatically and accurately set a wavelength to a peak position, by stopping the wavelength scanning of a spectrophotometer when a peak is detected by the wavelength scanning.

CONSTITUTION: A specimen to be measured is put in a specimen cell 2 and the wavelength of a spectrum peak thereof is inputted by a keyboard 9. CPU6 performs wavelength scanning to λ-Δλ of an input dispaly wavelength by the peak detecting program stored in ROM8 and thereafter performs pulse drive to λ+Δλ and takes in the output of a light detector 3 through an AD converter 4 and an input output port 7 to perform peak detection. When the peak is detected, wavelength scanning is stopped and the output of the light detector 3 at this time is printed by a printer 11 or stored in RAM5 along with the wavelength set by an operator. Therefore, a peak wavelength is automatically and accurately set.
