WebTo adjust the pH of a sample: 1. Prepare diluted sample. Most dilutions media such as buffered peptone water or Butterfield’s phosphate-buffered dilution water, have a level of buffering capacity and is designed to help buffer the pH. A pH adjustment may not be required after dilution. However, this should be determined during verification. 2. WebCarbonate materials and limestone are two elements that can buffer pH changes in water. Calcium carbonate (CaCO3) and other bicarbonates can combine with both hydrogen or hydroxyl ions to neutralize pH¹⁸.
