体积滴定法通常用于100 ppm至100%含水量范围内的样品, 虽然样品分析下降10 PPM水是可能的. 单组分卡尔菲舍尔试剂是最受欢迎的,因为它们是最便宜的, and don't always require a special solvent. In one-component Karl Fischer Titration, 已知浓度的滴定剂在容器溶剂中与样品反应, 最终消耗了样本中的水.

滴定剂含有KF反应所需的所有成分:碘, base, sulfur dioxide, and a solvent medium. 容器溶剂的选择要符合样品的溶解特性. 通过测量加入滴定剂的体积,可以计算出样品中的水量. Watermark产品线包括滴度值为5mg /mL的试剂, 2 mg/mL, and 1 mg/mL, covering an array of applications.

不含甲醇和吡啶的配方, 水印体积滴定剂适用于所有KF滴定样品, even those with aldehydes or ketones.

Not sure which to choose?

Choose a
One-Component System 如果你的实验室预算有限,或者经常进行KF滴定. All reactants are in the titrant bottle, 我们的水印非吸湿滴定剂的设计非常稳定,保证两年的保质期.

Choose a
Two-Component System 如果您需要更高的准确度,更快的滴定,或需要标准化频率更低. The lowest strength available is 0.5毫克/毫升,是专为最少的样品,或非常低的水含量的应用.

库仑滴定法通常选用含水量小于1%的方法, 虽然样品含水量高达5%是可能的. 阳极液和阴极液的选择是基于样品矩阵的, which in turn influences generator choice.

水印试剂为卡尔费歇尔滴定提供了最佳的价值和性能. With extended shelf life, rapid moisture determinations, and a stable end-point, 很明显,水印优于竞争对手. Watermark, by GFS Chemicals, 是专门配制的,以提供最终的分析性能.

 

卡尔费歇尔滴定剂的标准化是必要的,以确定其水当量. GFS化学公司生产各种参考材料, including primary standards in our Columbus, Ohio facilities.

Water standards 每盒10个一次性安瓿,并有5年的保质期. 水印水标准不含甲醇,可用于所有应用. 所有标准都附有分析证书(COfA)。, 是否经过ISO/IEC 17025认证的管理体系严格测试, and are NIST traceable.

Solid standards, including sodium tartrate and potassium citrate, are also available.

The Karl Fischer reaction is pH dependent. 大多数的水印滴定剂和溶剂被缓冲,以抵消样品,引起小的pH值变化. 如果样品导致pH值变化超出要求的5到7.5范围,副反应和慢动力学可能发生.

以抵消样品在极高或极低的pH值的影响, 加入缓冲材料将pH值调整到最佳pH值范围.

GFS化学专业生产无水高氯酸镁,它是空气和气体的优良干燥剂. KF滴定系统要求不受大气湿度的影响. 我们提供多种选择,包括分子筛, indicating silica beads, drierite and calcium-based desiccants.

比较一下我们的价格,看看我们是否能比你现在的供货商省钱.
