中文摘要本发明涉及一种被测物中元素组成及含量高低的识别方法,具体步骤为:1)建立元素标准谱图库;2)获取被测物的光谱,确定所测光谱波长范围;3)对被测光谱进行寻峰处理;4)判断所选元素在被测物中是否存在;5)存在某元素前提下,计算谱图的相关系数;6)根据相关系数高低判断元素浓度高低。本方法适用于激光诱导击穿光谱分析、火花直读光谱分析、荧光光谱分析等基于宽波段范围的原子发射光谱分析仪器。本发明能够快速判断被测物质中的元素组成,同时显示元素含量高低;而且可以同时判断多种元素,判断结果更准确,应用实现更容易。
英文摘要The invention relates to a method for identifying composition and content of elements in an analyte. The method comprises the following specific steps of: (1) establishing an element standard spectrogram library (2) obtaining a spectra of the analyte, and determining the wavelength range of the detected spectra (3) carrying out peak-seeking treatment on the detected spectra (4) judging whether the selected element exists in the analyte or not (5) calculating the correlation coefficient of the spectrogram under the premise that a certain element exists and (6) judging the element concentration of the elements according to the correlation coefficient. The method is suitable for an atomic emission spectroscopy instrument based on a wide band range for laser inducement breakdown spectroscopic analysis, scintilla direct reading spectroscopic analysis and fluorescence analysis and the like. The method provided by the invention can rapidly judge elemental composition in the measured substance, simultaneously displays the element content, and can simultaneously judge multiple elements and the judgment result is accurate, and the application and realization are easy.
