Abstract
At present, the photometric method uses multiple standard samples to draw "calibration curves" to determine the results of sample measurement. However, the difficulty of preparing multiple standard samples has become a major obstacle to the popularization and application of spectrophotometry. The results show that if the spectrophotometric determination process strictly follows the "precision rule", i.e. “to maintain infection consistency of each factor for each sample(including standard sample) in the same measurement series ”, then in the "calibration curve" , that is, in the domain of incident light. the absorbance difference ΔA of chemicals proportional to its content difference ΔC: ΔA = KΔC. The coordinate points (C, A) of content and absorbance of all the samples, must in the same ΔA = KΔC article line. Therefore, the line between the upper and lower coordinates of the standard sample is the "proportional determination line" of the sample content. Relative standard deviations of 10 determination results of Mn, Si,P were : 2.26%,3.63%,6.45%,and the uncertainties were: 0.04%,0.03%,0.005%(k=2), respectively. In this paper, the implementation details of the "Precision Rule" in spectrophotometry are introduced, which provides the basic operation technology for the popularization and application of spectrophotometry.
