摘要
本文对自动分析仪的"样本携带污染率"的测试方法和计算公式进行了分析,证明样本携带污染率K,是自动分析仪内部上一个样本的残留量相对于下一个样本的输入量加上一个样本的残留量的总体积比,提出了使用"样本携带污染率"计算公式修正测试值的见解。分析了在测试方法上自动分析仪的随机误差对"样本携带污染率"测试值的影响,建议采用多次测试的均值,避免仪器随机误差对测试结果的影响。
Key words In this paper, analyses the test methods and formula of the sample carryover rate, tested by an automatic analyzer. Through this, proved that the sample carryover rate K is a volume ration, the sample residues relative to the total volume of the next sample input and the previous sample resides. Proposed the use of ＂sample carryover rate＂ formula fix the value of the test result. Analyze of the test methods of random errors affect on the ＂sample carryover rate＂, the mean of several sample tests result recommended to avoid random deviation on the test results.
