WebThere are a couple of rules of thumb to follow: #1 For best results, use a buffer that has a pH at least 2 units away from the pKa for the analyte of interest. If the pH of the mobile phase is too close to the analyte’s pKa, you might observe split peaks or shoulders. WebA buffer solution is prepared as a combination of weak acids and their salts (sodium salts, etc.) or of weak alkalis and their salts. Common preparation methods include: 1) dripping an acid (or alkali) into an aqueous solution of a salt while measuring the pH with a pH meter and 2) making an aqueous solution of acid with the same concentration ...
