WebBuffer . If the buffer property is set, a buffer stream will show with animated circles to indicate activity. The value of the buffer property will also be represented by how much visible track there is. If the value of buffer is less than the value property, there will be no visible track. If buffer is equal to 1 then the buffer stream will be hidden. Web19 apr. 2024 · Buffer is a solution of a weak base and its conjugate acid or weak acid and its conjugate base. They reduce the effect of hydroxide and hydrogen ions and reduce pH fluctuations upon dilution. Usually, the range of pH is 2.00 to 8.00 for RP-HPLC on silica-based packing. The selection of a buffer solution is usually governed by the preferred pH. incite violence synonym
