Abstract

PURPOSE:To improve detection sensitivity, by adding the object matrial of a known concentration to the object material of a low concentration to analyze this material as a high-concentrating material in case that the object material is low-concentration, in analysis dependent upon the detection system where detection sensitivity is low and high for the low-concentration region and the high-concentration region respectively. CONSTITUTION:In the analysis method of an analysis object material dependent upon the detection system where detection sensitivity for the analysis object material included in a sample is low and high for the low-concentration region of the analysis object material and the high-concentration region respectively, in case the true concentration of the analysis object material included in the sample is low, the analysis object material is previously added to the sample by a known bias concentration, and the overall concentration of the analysis object material in the sample is detected in the high-concentration region where detection sensitivity is high, and the bias concentration is subtracted from the detected overall density to obtain the true concentration of the analysis object material included in the sample. As a result, the concentration of the object material is detected in the high-sensitivity region, so that detection sensitivity can be enhanced, and a high-precision measurement is possible.
