WebNov 1, 2024 · Britton Robinson (BR) buffer pH 5.0 was found to be suitable medium with E 0 value of 1.0 V (Fig. 2). The method was developed by applying mobile phase as BR buffer (pH 5.0) and methanol (93 : 7 v/v) mixture with isocratic flow at 0.5 mL/min, with the autosampler and column oven maintained at 4°C and 35°C, respectively. WebFeb 20, 2016 · Britton-Robinson buffer is a multi-buffer system that consists of citric acid, phosphate, barbital, and boric acid. Although this buffer system is known to be effective from pH 2.6 to 12, the linearity of the alkaline region (pH 9–12) is poor. Searching for a weak acid additive to maintain the buffering capacity in the alkaline region, we found that …
