认证:
此滴定溶液由我们获得DAkkS(Deutsche Akkreditierungsstelle,德国国家认证机构)DIN EN ISO/IEC 17025标准的滴定溶液物质的量浓度分析认可的校准实验室D-K-15185-01-00分析。认证证书请见www.sigmaaldrich.com/ISO17025.

Analysis Note

形态:液体
物质的量浓度:0.0994 - 1.006 mol/L
测量不确定度± 0.0004 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符合ISO 17034的认证标准物质苯甲酸基准试剂(货号1.02401)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 350苯甲酸),由我们的DIN EN ISO/IEC 17025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。
