Analytical Quality Assurance


All measurement results can be defective. In chemical analytics, the possible error sources can be either the reagents, the instruments, the operation and the sample composition (matrix).

The Analytical Quality Assurance (AQA) guarantees to eliminate these error sources as far as possible. For many years, WTW has been offering the user top-quality reagents with lot certificates and a complete range of testing aids for photometer and pipette.
