EIL matrice solideOne of the main issues when implementing proficiency tests with a solid matrix is to obtain a sufficient batch homogeneity. AGLAE has implemented proficiency tests in raw solid matrices and in pretreated solid matrices for metals and organic micropollutants (PAHs) in order to check if the raw materials could be homogeneous enough to be employed during proficiency tests.
