Phosphate buffers can be replaced by ammonium formate (pH 2.8–4.8), ammonium acetate (pH 3.8–5.8), or ammonium bicarbonate (pH 8.2–10.2). Figure 10(a) shows a chromatogram for a neutraceutical mixture using a phosphate-buffered mobile phase. When phosphate is replaced with formate at ...
This study evaluates the solubility of AAU nephroliths in a phosphate buffer, pH range 6.0-8.0, and in a carbonate-bicarbonate buffer, pH range 9.0-10.8. AAU nephroliths were obtained from six dolphins and solubility studies were conducted using reverse-phase high performance liquid chromatography...
For the adjustment of the pH, preferably to a physiological pH, buffers may especially be useful. Examples of buffer substances are acetate, ascorbate, borate, hydrogen carbonate/carbonate, citrate, gluconate, lactate, phosphate, propionate and TRIS (tromethamine) buffers. Tromethamine and borate buffe...
