Given the crucial nature of sampling and analysis for the correct determination of a product’s purity/impurities, the MMTA, along with the vital contribution of our Member sampling and analytical companies, have drawn up best practice guidelines for the sampling of our materials, in all forms, and the resultant analyses.
Our member sampling and analytical companies will therefore use these best practice guidelines for the work they carry out on behalf of the Membership, and they are detailed on these pages for all interested parties.
Any disputes which may arise concerning sampling and analysis are strictly between the company who instructs such sampling/analysis and the sampling and analytical company(ies) who carry out the operations.
