Method and device for quickly screening peak value batch data of fluorescence spectrum

Abstract

This application provides a method and device for quickly screening peak value batch data of a fluorescence spectrum. The method comprises the steps that three-dimensional fluorescence spectrum data of at least one sample to be analyzed is obtained; a fluorescence emission wavelength range and excited light wavelength range of at least one DOM component are obtained; position point calibrating iscarried out on fluorescence spectral peaks of each group of spectral data in a current display screen of a display assembly, and boundary regions are delineated for each DOM component; whether position points of the fluorescence spectrum peaks are distributed in each boundary region or not is detected, and the target fluorescence spectrum peaks of each DOM component are determined according to detection results; and screening results of the fluorescence spectrum peaks are obtained by summing up the data of all target fluorescence spectrum peaks. The method is low in operation difficulty and high in generalization, the distribution position of the fluorescence spectral peaks of all DOM components in all samples to be analyzed can be quickly and accurately determined, and the corresponding visualization effect is provided so as to intuitively realize the whole screening process of the fluorescence spectral peaks.

Description

Technical field [0001] This application relates to the technical field of three-dimensional fluorescence spectrum data screening, and in particular to a method and device for rapidly screening batch data of fluorescence spectrum peaks. Background technique [0002] With the continuous development of science and technology, three-dimensional fluorescence spectroscopy (Three-Dimensional Excitation-Emission Matrix Fluorescence Spectra, 3DEEM) technology has been widely used due to its advantages such as low sample consumption, high repeatability, high sensitivity and no damage to sample structure. Organic matter (Organic Matter, OM) testing field, used to test substance samples (for example, soil, water or sediments in a certain area) for dissolved organic matter (DOM) component analysis, material source analysis and Study on the biochemical characteristics of the law of material migration and transformation. [0003] Among them, in the process of using three-dimensional fluorescence...

Problems solved by technology

At present, the mainstream in the industry usually adopts manual determination method or parallel factor analysis method to determine the distribution position of fluorescence spectrum peaks. Among them, the manual determination method is time-consuming, consumes a lot of human resources, is not intuitive and has low accuracy, etc. Disadvantages: Parallel factor analysis requires operators to have strong professional knowledge. It is difficult for ordinary personnel to determine the position of fluorescence spectrum peak distribution based on parallel factor analysis. The overall generalization and intuition are not strong.
