五日空白平行试验批内标准偏差及检出限计算

Calculation on Batch Standard Deviation and Detection Limit of Five Day's Empty Parallel Test

文章通过两种计算方法 ,对分光光度法测 NOX和 SO2 的空白平行试验批内标准偏差和检出限计算进行了探讨 ,指出在环境监测质量控制中 ,用吸光度直接计算是较好方法。

Through two calculating methods, this paper probes into the calculation on batch standard deviation and detection limit of the empty parallel tests on NO X and SO 2 measurement by using spectrophotometry, pointing out that the direct calculation with absorbency is a better method in environmental monitoring quality control.
