      标准物质是直接影响测定准确度的重要因素。此外,重复的测定成本昂贵并且浪费时间。这是新蓝景为客户提供认证缓冲物质和溶液的原因。

      最高品质的二级标准缓冲液最大误差是±0.003PH单位,非常精确并且适合用于仪器监控

      即用型缓冲溶液和Titrisol缩液

      即用型缓冲溶液的认证测量不确定值是0.015 pH单位,非常适合日常实验室使用。同样,Titrisol浓液的测量不确定值是0.02 pH单位.

      即用型袋装缓冲液

      即用型袋装缓冲液不仅可以确保结果精确,而且有不易污染和保持新鲜的优点。

      新蓝景拥有自己的PH测定校准实验室

      新蓝景自己的pH测定校准实验室已经经过校准协会(DKD) DKD-K-14301,方法认证,而且接受DKD或联邦物理技术研究所(PTB]的严格审计。所有新蓝景的缓冲物质和溶液都接受这个实验室的质里检侧。

      质量控制

      新蓝景二级标准物质经过双铂氢电极示差电势测定法检测。该方法测定pH的总体不确定值最大是±0.003 pH单位,因此缓冲液配制可以非常的精确。

      为了确保即用型缓冲溶液.Tritisol 浓缩液或袋装液的精确测量,新蓝景采用了5点校准法(精度为≦±0.015个pH单位或者±0.02个pH单位);这种方法比简单的2点法校准精度(≥0.05 pH单位)更高。

      溯源性

      我们的标准物质可以直接溯源到美国国家标准与技术研究所(NIST)和联邦物理技术研究所(PTB]的一级标准物质,因此PeltoPUR标准缓冲物质和溶液具有双重溯源性。

      PeltoPUR二级标准缓冲溶液(25 `C) PeltoPUR Secondary standard buffer solution(25 `C)

      该系列产品用于校准并监控PH测定仪。

      最大误差仅有0.003pH单位。每个PeltoPUR产品都在它的COA中提供有相关数据。

      为您提供精确并节省时间和成本的产品。

      新蓝景公司提供给PT8分析用的缓冲物质,PT8在经过严格的测定后再将它们制成基准物质。这样的基准

      物质对于客户来说过于昂贵,因而新蓝景采用同样的原材料制成二级标准物质提供给客互,并用基准物质

      对其比较定值。

      此外。PeltoPUR缓冲液/物质均通过NIST的一级标准物质比较定值。
