滴定 - 容量法标准物质
准确的滴定度测定是精确和可比滴定分析的重要标准。Certipur® 用于容量标准的产品包括用于酸度计、碱度计、精氨酸计、络合度计、碘度计和氧化还原滴定的高纯度二级标准物质。容量标准物质是实现容量溶液标准化以产生可靠结果的最佳选择。它们根据药典中的试剂部分进行生产和广泛测试，并按照 ISO/IEC 17025 和 ISO 17034 标准以尽可能高的精度进行测量。
颜色参照解决方案
为了校准和验证测试数据，我们的产品组合包括各种经认证的参照材料，用于 颜色溶液符合各种药典，如 USP、EP 或其他颜色测量标准、
BOD/COD, TOC
BOD （生物需氧量） 是微生物分解废水中有机物所消耗的氧气量。COD（化学需氧量）是指氧化水或废水中的有机污染物所需的氧气量。TOC（总有机碳）已成为一个重要参数，用于监测废水中有机化合物总碳含量的总体水平。
对于这些分析，我们提供经过认证的标准物质和分析级标准，作为校准用的即用溶液以及 CRM 基质材料。
pH 缓冲溶液参考材料
缓冲溶液是一种化学物质，在加入酸或碱后可保持溶液的 pH 值恒定不变。缓冲溶液对于维持 pH 仪器的正确校准也至关重要。pH 测量的准确性直接受到校准过程中使用的缓冲参比材料的影响。Certipur® 认证缓冲溶液和参考物质已通过 ISO 17034 和 ISO/IEC 17025 认证，可为您提供最高的准确性、可靠性和便利性，同时确保结果一致，避免昂贵的重复分析。
在我们的pH-缓冲液产品组合中可以找到与所有 pH 仪器兼容的用于常规监测和校准 pH 仪器的高质量标准物质，如一次性小袋装、即用型溶液（有色或无色）和纯净的缓冲液物质。
