基层疾病预防控制中心所承担的检测工作面广、工作量大,对于日常工作中的定量检测,大都是利用工作曲线来进行的。在进行原子吸收和色谱分析时每次都要进行标准系列的测定,以保证结果的可靠。但在常规的比色分析中,往往并不能做到每次分析都做工作曲线,而是同一项目同一批试剂共 The primary disease prevention and control center has a wide range of testing work and a heavy workload. Most of the quantitative tests in daily work are carried out by using the working curve. A standard series of measurements should be performed each time you perform atomic absorption and chromatographic analyzes to ensure a reliable result. However, in conventional colorimetric analysis, often do not do every working curve, but the same project with a total of reagents
