TestQual is an spanish company specialised in quality assurance for laboratory research. We have been more than ten years organising, distributing and reporting chemical proficiency studies. These proficiency studies compare the results from laboratories all over the world, so each laboratorie can measure its analytical proficiency and test the quality of its analyses.

TestQual also produces reference materials, always certificated, tested and guaranteed for homogeneity and stability. These materials are used to check the quality of analyses.
