分析報告
物质的量浓度:0.0995 - 0.1005 mol/L
测量不确定度± 0.0003 mol/L
可溯源至NIST SRM
浓度通过容量滴定法在20℃测定。
此滴定溶液的物质的量浓度是使用ISO 17034标准的认证参考物质三羟甲基氨基甲烷基准试剂(货号1.02408)标定的,并可溯源至美国盖瑟斯堡国家标准技术研究所的一级标准参考物质(SRM)(NIST SRM 723 三羟甲基氨基甲烷),由我们的DIN EN ISO/IEC 17025标准认可的德国达姆施塔特默克校准实验室负责分析。不确定度表示为扩展的测量不确定度,覆盖因子k = 2,覆盖95%的置信度。
注意:滴定度是一种用于校正容量滴定溶液、滴定设备、温度和其他实验室条件变化的校正因子。为了获得正确的滴定结果,建议在打开新瓶后并在一定时间间隔内,立即使用实验室专用设备并在实验室特定条件下对滴定度进行确定。

实验方案
APHA 10200-H describes a measurement against an extraction solution. When the method was zeroed using the stated reagents, no difference in absorbance was found compared with zeroing the method using water for analysis. It is hence possible to use water for analysis to zero the method.
Method: Spectrophotometric Color Determination at 420 nm Zero adjustment For each measurement series, a zero adjustment is required. It is recommended to use the same cell for zero adjustment and for sample measurement. The zeroing procedure for the measurement series is automatically prompted by the instrument after entering the %RDS value.
