詳細

Potassium hydrogen phthalate, also known as KHP, is a volumetric standard manufactured under stringent conditions and measured with the highest possible precision. Its mass fraction is determined by potentiometric titration, and it is qualified in a DIN EN ISO/IEC 17025 accredited laboratory.

Please visit ISO certificates and Site Quality Self-Assessments to access the current certificates of accreditation.

In our effort to be more sustainable, we′re going digital with COAs-download them directly from our website. Download your certificate at http://www.sigma-aldrich.com to view certified values, including uncertainty and expiry date.

アプリケーション

It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in alkalimetric titrations, according to Ph. Eur. It is also used to prepare a standard solution in determination of COD.

特徴および利点

  • Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
  • Certified reference material according to ISO 17034
  • High-purity material traceable to NIST SRMs
  • Qualified in a DIN EN ISO/IEC 17025 accredited laboratory
  • In accordance with the chapter reagents of Ph. Eur
  • High-quality offering accurate titer determinations

資料

The titer determination or standardization of a titration solution is essential for accurate and reliable titration results. High quality solutions verified by high quality standards are the base for a reliable determinations.

SmartChemicals enable wireless transfer of CoA data stored on an RFID tag on the consumable bottle to the titrator, reducing effort and chance for human error. Crucial data required for the application is transmitted safely, reliably and intelligently to the instrument.
