The value of the chemical measurement depends upon the degree of confidence that can be placed on the results. Increasingly, quality assurance principles are being applied. These do not actually guarantee the quality of the data produced, but increases the possibility of these results being soundly based.

Appropriate quality assurance can enable a laboratory to show that is has adequate facilities, and equipment for carrying out chemical analysis. It also enables the laboratory to show that competent staff carried out the work in a controlled manner, following a documented validated method. Quality assurance should focus on the key issues, which determine quality.
