Title:
LAMP LIGHTING DEVICE, FLUORESCENCE DETECTOR, AND CHROMATOGRAPH
Document Type and Number:
WIPO Patent Application WO/2023/132265
Kind Code:
A1
Abstract:
This lamp lighting device is used for lighting a discharge lamp provided in a fluorescence detector as a light source. The discharge lamp has a configuration in which an anode and a cathode are arranged facing one another in a discharge vessel. The lamp lighting device includes a lamp drive unit, a lamp voltage detecting unit, and a degradation determining unit. The lamp drive unit drives the discharge lamp. The lamp voltage detecting unit detects a lamp voltage during a monitoring period after the discharge lamp in an extinguished state has been lit by insulation breakdown, until a discharge state reaches a predetermined steady state. The degradation determining unit determines a state of degradation of the discharge lamp on the basis of the detected lamp voltage.
