Document Type and Number:
WIPO Patent Application WO/2014/030475
Kind Code:
A1
Abstract:
The purpose of the present invention is to effectively use the light of a light source of a spectrophotometer and thereby extend the period of use of the light source and achieve a reduction in the power consumed by the device. A spectrophotometer has a sample-chamber lid capable of opening and closing an opening in a sample chamber for placement of a sample and a reference sample, and a sample-chamber-lid open/close detecting means for detecting the open or closed state of the sample-chamber lid, and is capable of measuring and controlling a xenon flash tube as a light source, as well as a spectrometer, detector, amplifier, AD converter, processor, storage device, and data display unit, wherein the spectrophotometer is characterized in that: the fact that the lid is closed from an open state is detected by the sample-chamber-lid open/close detecting means in the sample placement command mode; the light source is turned on; an absorbance, transmittance, reflectance, sample-side energy value, or reference-side energy value is measured; and the measurement result is displayed on the data display unit.
