pH buffer solutions serve as essential reference points for the calibration and adjustment of pH measurement instruments. They help compensate for sensor aging and performance deterioration, ensuring consistent and reliable pH readings over time.

As an indispensable tool in pH measurement, buffer solutions are used to maintain accuracy by providing stable, known pH values during calibration. Without accurate buffer solutions, the calibration process becomes ineffective and unreliable.

pH buffer solutions are formulated from mixtures of weak acids and their corresponding salts with strong bases, or weak bases and their corresponding salts with strong acids. Because calibration accuracy depends entirely on the quality of the buffer, the precision and stability of the buffer solution are critical.

Buffer solutions are generally classified into three categories, distinguished mainly by their accuracy and buffering capacity.
