Choose a buffer based on your pH requirements as well as the pKa, a measure of acid strength that accounts for pH, concentration, and temperature. Regulatory or purity needs for your exact application should also be considered. The following tables can help you navigate preparation of many common buffer solutions by pH and pKa.

A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it.

2010年3月17日 · High pH buffers. Discussions about HPLC, CE, TLC, SFC, and other "liquid phase" separation techniques.

From enhancing reaction accuracy in research labs to supporting biotechnological advancements, these PH buffer solutions are critical for enabling reliable outcomes across numerous disciplines. That’s why we offer a diverse portfolio of high-performance …

The buffer must have a pKa close to the desired pH, since buffers control pH best at their pKa. As a rule of thumb, it is ideal to choose a buffer with a pKa value <2 units of the desired mobile phase pH. We offer HPLC grade buffers for a wide pH range for all your lab chromatographic requirements. ... High-quality solvents and reagents are ...
