Quality: overview ring tests

As part of ensuring a constant control and improvement of quality, Primoris takes part in many national and international ring tests. These are independent checks on the quality of laboratory analyses. On the basis of these ring tests, the performance of the analytical method is evaluated and, if necessary, improved. Some of these ring tests are registered 'undercover' in order to meet the highest possible quality standards.

Annual audits, the use of undercover ring test samples and constant evaluation of competence and customer support levels are just some examples of how the highest possible guarantee on reliable analyses and high quality support can be pursued.
