Dibutylammonium phosphate
WebThe mobile phase consisted of dibutylammonium phosphate buffer and acetonitrile (55:45, v/v) was used at the flow rate of 1.0 mL/min. Dibutylammonium phosphate buffer was prepared by dissolving 1.7 mL of dibutylamine and 3.0 g of phosphoric acid in 900 mL of water and the pH was adjusted to 6.5 ± 0,05 with sodium hydroxide 50% (w/v). WebDibutylammonium phosphate (DBAP) buffer solution, 1 M: Add 168 mL dibutylamine to 700 mL of water. Slowly add approximately 120 mL concentrated phosphoric acid to adjust the pH of this solution to 2.52.6. Dilute - solution to 1 L with water. Filter under vacuum.
