Certification of Reference Materials of Maize Seed Powder with different Mass Fractions of Genetically Modified 98140 Maize, ERM-BF427 (ERM-BF427a, ERM-BF427b, ERM-BF427c, ERM-BF427d)

Abstract

This report describes the processing and certification of four maize seed powder Certification Reference Materials (CRMs) containing different mass fractions of genetically modified (GM) DP-ø9814ø-6 maize (ERM-BF427a, b, c, d), according to the principles of ISO Guide 34. The certification values were confirmed by event-specific real-time PCR as independent verification method. The CRMs are intended to be used for quality control of calibration of methods for the quantification of the DP-ø9814ø-6 maize mass fraction in food and feed. The four CRMs have been accepted as European Reference Materials (ERM) after peer evaluation by the partners of the European Reference Materials consortium.
