General description
A zwitterionic buffer useful in the pH range of 5.5-6.5 (absorbance: <0.05 at 260 nm, 100 mM, H2O; pKa: 6.2 at 20°C).
Absorbance (100 mM, H2O, 260 nM):≤0.05.
Application
- Galvanic cell without liquid junction for potentiometric determination of copper.: This study presents the use of a galvanic cell without liquid junction for the potentiometric determination of copper ions. This method can be adapted for use with MES sodium salt buffers in analytical chemistry, offering a stable and reproducible way to measure copper concentrations in various media (Migdalski et al., 2007).
- Oxygen solubilities of media used in electrochemical respiration measurements.: This research explores the oxygen solubility in various media used for electrochemical respiration measurements, which includes the use of MES sodium salt buffers. It highlights how different buffer systems affect oxygen solubility and the implications for biochemical studies involving cellular respiration (Rasmussen HN et al., 2003).
Preparation Note
