Sodium hydrogen carbonate/sodium carbonate

产品说明

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 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

Sodium hydrogen carbonate/sodium carbonate [pH(S) = 10.012 (25℃)] is a certified secondary standard reference buffer 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 relevant data for the quality management system.
• The pH value of this Certipur^® buffer solution is measured using differential potentiometry with two platinum hydrogen electrodes against NIST & PTB primary SRM [pH(S) = 10.012 (25 ℃)].
• It is a Certified Reference Material (CRM) offered in neat format.
• Intended for extremely precise calibration, qualification and monitoring of pH instruments and for testing other buffer solutions.
