The group of complex matrices is a very heterogeneous group of matrices (like milk, spices, sugar crops, oil containing seeds, ...) so there is no specific certification for complex matrices in general.
Specific for tobacco, Primoris takes part in the working group of Coresta (Cooperation Centre for Scientific Research Relative to Tobacco) and follows their guidelines in matters of pesticide residues in tobacco.
Please contact us if you have questions about the accreditation of an analysis method of a complex matrix.
