Laser being induced fluorescent method and the laser being induced fluorometric analysis

摘要

PROBLEM TO BE SOLVED: To provide a laser induced fluorescence analysis method and a laser induced fluorescence analysis probe for heightening the reproducibility of analysis values by correcting variations in the light intensity of laser induced fluorescence due to a selected pumped laser beam irradiating a sample.;SOLUTION: The laser induced fluorescence analysis probe is provided in the probe with a light intensity detector 1 for detecting the light intensity of laser induced fluorescence and a light intensity detector 2 for detecting the light intensity of part of a selected pumped laser beam. The light intensity F of fluorescence and the variable light intensity L' of the selective pumped laser beam are measured to correct the concentration of elements to be analyzed by a ratio of light intensity F/L' and determine the concentration in the laser induced fluorescence analysis method and the laser induced fluorescence analysis probe. It is possible to stably, continuously determine the concentration of components without being affected by energy variations of the selective pumped laser beam irradiating the sample.;COPYRIGHT: (C)2009,JPO&INPIT
