仪器分析中常用定量方法研究

Brief Study on Instrument Analysis Quantitative Methods

仪器分析是以物质的物理性质和物理化学性质为基础而建立起来的分析方法。定量是仪器分析的目的,可以准确计算出待测组分的含量,但影响定量方法准确度因素很多,分析工作者需要了解仪器分析各方法的适用性、灵敏度和准确度,才能在解决某个具体问题的许多途径中作出合理的选择,提高分析问题和解决问题的能力。本文归纳总结《仪器分析》这门课程中所涉及到重要定量分析方法的异同点,并且对不同的定量分析方法进行比较。

Instrumental Analysis is based on the physical and physicochemical properties of materials. Quantitative is the purpose of Instrument Analysis,can accurately calculate the content,but many factors influence the accuracy of quantitative methods. In order to solve a specific problem to make rational choices in many ways,workers need to understand the applicability of various methods of Instrumental Analysis,sensitivity and accuracy. The similarities and differences of the important quantitative analysis methods in course of Instrumental Analysis were summarized,and the different quantitative analysis methods were compared.
