Fungicides (Food Additives) Quantitative Reference Materials
Fludioxonil, Azoxystrobin, Pyrimethanil

Fludioxonil, azoxystrobin, pyrimethanil were designated as food additives (fungicides) in accordance with the partial revision of "Ordinance for Enforcement of the Food Sanitation Act (Ordinance of the Ministry of Health and Welfare No. 23, 1948) and Specifications and Standards for Food, Food Additives, etc., (Ministry of Health and Welfare Notification, No.370, 1959)".
Along with this, the specifications and standards for fludioxonil, azoxystrobin and pyrimethanil were established as food additives, and qNMR method was applied as the method for purity analysis for quantitative reference materials used in the quantitation method (purity assessment for food additives).
We provide standard materials for fludioxonil, azoxystrobin and pyrimethanil assessed for purity with use of qNMR method (purity assessment method for quantitative reference materials).

* Assessed for purity by National Institute of Advanced Industrial Science and Technology Metrology Research Center : National Metrology Institute of Japan (NMIJ).
