Calibration Buffers and Standards

GMP, GLP, ISO 9001, EN 45000, calibration, verification, traceability, certification from an accredited organization: key words that are increasingly important. The calibration of pH and Redox electrodes has never been easy. All calibration procedures assume that the labeled values of the calibration buffers are correct. But buffer values can change over time and so can your results.
