一般描述

Certipur^® certified secondary standard reference buffers are used to precisely calibrate and monitor pH measurement instruments and buffer solutions. They are quality controlled and qualified in our ISO/IEC 17025 and ISO 17034 accredited calibration laboratories against certified primary standard reference materials (SRM) in compliance with DIN 19266, IUPAC, NIST, Ph. Eur and USP. Certipur^® reference materials offer maximum accuracy, reliability and convenience and help avoid costly repeat analyses.

应用

Potassium hydrogen phthalate [KHP; pH(S) = 4.00₅ (25 ℃)] is a certified secondary standard reference material used as a calibration buffer standard for pH instruments or pH electrodes.

特点和优势

• The product is delivered with a comprehensive, batch-specific Certificate of Analysis showing the relevant data for the quality management system.
• The pH value of this Certipur^® buffer solution is qualified using differential potentiometry with two platinum hydrogen electrodes against NIST & PTB primary reference materials [pH(S) = 4.00₅ (25 ℃)].
• This buffer standard has a guaranteed shelf life of 4 years.
• Potassium hydrogen phthalate buffer is a Certified Reference Material (CRM) offered in neat format. Solution of this standard can be prepared in-house per instructions in European Pharmacopoeia (Ph. Eur. 2.2.3).
• Intended for extremely precise calibration, qualification and monitoring of pH instruments and routine assessment of their performance.
