Abstract

PURPOSE: To obtain a titled detector which can detect solute concn., etc. with high sensitivity by combining a sensor consisting of piezoelectric element, etc., a light source part, an acoustooptic filter system modulator, etc., irradiating light to the flowing fluid to be measured, and measuring the optical sounds produced by this.
CONSTITUTION: A pressure sensor povidied with a piezoelectric element such as piezoelectric ceramic is provided in a flow cell 4, and is combined with a light source part 1, an acoustooptic filter system modulator 2, a lens 3, etc., whereby an intended flow type optoacoustic detector is obtained. The laser light from the light source part 1 is modulated to an arbitrary frequency by the modulator 2, after which it is focused by the lens 3, and irradiates the liquid to be detected in the flow cell 4. Thence, the generated optical sounds are detected with the pressure sensor and are amplified with a lock-in amplifier 5, after which they are recorded with a recoder 7, whereby the presence or absence of solute in the liquid to be detected or the concn., etc. of the solute is measured with good accuracy.
