Ph of 1n sodium hydroxide
WebbAccording to the PDA Biotechnology Cleaning Validation Committee (see Reference 3), concentrations of 0.1 to 1.0 M sodium hydroxide are common for storing packed chromatography columns. Removal of sodium hydroxide can be determined by simple in-line pH and conductivity measurements. WebbCurrently, we use 100 mM ammonium hydroxide, which is not very well buffered. For our compounds, pH 11 seems to be optimal because we cannot reduce the aqueous composition down to 10 mM (pH...
