摘要
There is provided that enables high-sensitivity analysis to be carried out, and a photothermal conversion spectroscopic analysis apparatus that is compact in size and is able to implement the photothermal conversion spectroscopic analysis method. Exciting light and detecting light are convergently irradiated onto the sample by a converging lens. The sample is analyzed using a change in intensity of the detecting light due to refraction upon passing through the thermal lens produced through the convergent irradiation of the exciting light. A molar absorption coefficient of the sample at a wavelength of the exciting light is a predetermined number of times greater than a molar absorption coefficient of the sample at a wavelength of the detecting light.
