在环境监测中使用分光光度法进行样品测定时,都要利用校准曲线的回归方程计算其待测样品的含量。为使监测结果更为准确,必须对校准曲线的准确性进行检验,即对校准曲线的斜率进行统计检验。在实际工作中,常采用 Dixon 检验法和斜率相对偏差(RbD)法检验校准曲线斜率,也可以利用校准曲线斜率均值控制图进行质量控制,使分析测试工作处于受控状态中,使监测结果更加真实可靠。
在環境鑑測中使用分光光度法進行樣品測定時,都要利用校準麯線的迴歸方程計算其待測樣品的含量。為使鑑測結果更為準確,必鬚對校準麯線的準確性進行檢驗,即對校準麯線的斜率進行統計檢驗。在實際工作中,常採用 Dixon 檢驗法和斜率相對偏差(RbD)法檢驗校準麯線斜率,也可以利用校準麯線斜率均值控製圖進行質量控製,使分析測試工作處于受控狀態中,使鑑測結果更加真實可靠。

When the sample was measured by spectrophotometer in environmental monitoring, the regression equation of calibration curve was used to calculate content of the sample. To obtain more accurate results, the accuracy of the calibration curve must be tested, i.e. statistical tests for the slope of the calibration curve. Dixon test and the test for relative standard deviation of slope were often used in the practice. In addition to these two tests, control chart for slope mean value was also used to control quality, which made analytical testing in a controlled state and monitoring results more reliable.
