Welcome

TestQual is a Spanish company specialised in quality assurance for laboratory research. For fifteen years we have been organising, distributing and reporting chemical proficiency studies. These proficiency studies compare the results from laboratories all over the world, so each laboratory 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.
