摘要
标准曲线外标法是许多检测中常用的一种分析方法,分光光度计是由样品浓度（或含量）和Abs（吸光度）值组成的标准曲线法。在Abs值的范围要求方面,经过系列试验,得出Abs值在0.01~0.35之间标准曲线非常稳定且重现性好。通过对低Abs值标准曲线的F值检验、t值验检、相关系数、样品检测及仪器管理角度的分析,得出结论低Abs0.01~0.35值标准曲线在现实检测中可行。
External standard method of the standard curve was used in various detection. A spectrophotometer is the standard curve method composed of the sample concentration（or amount） and Abs（absorbance） value. In the range of requirements, authors indicated that the standard curve was very stable and reproducible when Abs value was between 0.01 and 0.35 through series of tests. By analysis of F value test, t value test and correlation coefficient for low Abs value standard curve, sample testing and equipment management, authors concluded that low Abs value of 0.01 ~ 0.35 standard curve were feasible in practical detection.
