基本信息
| General description【一般描述】 | The certified buffer solution (boric acid/sodium hydroxide/hydrogen chloride) is gravimetrically prepared using high-quality reagents following DIN EN ISO/IEC 17025. Its pH value of 8.00 at 20℃ is measured following a 5-point calibration method, using a combined glass electrode. The measurement is made following DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. Its pH value is strongly dependent on the temperature and therefore a constant temperature must be maintained during its use. |
| Application【应用】 | The buffer solution is meant to be used as a calibration standard in analytical procedures for pH measuring instruments or pH electrodes and as a control for measuring the pH of solutions. |
