| Other Notes: | Example analytes are listed below as a reference. Please download a current certificate at nist.gov/SRM for current analytes and certified values. |
| Other Notes: | The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution. For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode. |
