Abstract

PURPOSE:To detect the light acoustic effect output obtained and the output obtained by photoelectrically converting the fluorescence radiated again from the sample, simultaneously by illuminating the light onto the sample disposed in the sample chamber connected to the base chamber through the gas passage in which the thermal flow detecting element is disposed. CONSTITUTION:The sample chamber 3 of the detector A and the base chamber 4 are connected by the gas passage 5 and at the outlet side of the gas passage, the thermal flow meter type detectingelement 9 is mounted. The sample 2 is placed in the sample chamber 3 and the homogeneous light is illuminated through the light transmission window 6 as an intermittent light of a constant frequency by the light chopper B. The pressure of the gas due to the thermal expansion of the ambient gas by the sample is detected by the detecting element 9 and it is fed to the operation amplifier C as a signal a indicating the acoustic effect output and further operation processed together with the signal indicating the wave length and the strength emitted from the light chopper B and transmitted to the indication amplifier D. The fluorescence reradiated from the sample 2 is detected by the fluorescence detector 11 and the electric output signal is operation processed by the operation amplifier F and fed to the indication recorder D. In this manner, the thermal quality and the optical property due to the light absorption of the sample are simultaneously determined.
