THERMAL LENS SPECTROMETRIC ANALYTICAL SYSTEM, AND THERMAL LENS SIGNAL CORRECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a thermal lens spectrometric analytical system and a thermal lens signal correction method, which measure accurately a sample, even when thermal lens signal intensity is varied by an external environment change.;SOLUTION: This thermal lens spectrometric analytical system 10 is provided with: a micro chemical chip 2 having a groove 1 injected with the in-liquid sample in an inside; a refractive index distribution type rod lens 3 for converging excitation light and detection light propagated from a light source unit 7 via an optical fiber 5 to the liquid sample to generate a thermal lens image; a photoelectric converter 22 for detecting light quantities of the excitation light and the detection light, and the thermal lens signal intensity; and a personal computer 25 for correcting a measured value of the thermal lens signal intensity, by multiplying the measured value of the thermal lens signal intensity with the first ratio (prescribed light quantity of the excitation light/measured light quantity of the excitation light), and/or the second ratio (prescribed light quantity of the detection light/measured light quantity of the detection light).;COPYRIGHT: (C)2007,JPO&INPIT
