Organic, Inorganic, Microbiology & PT Reference Materials for Food & Agriculture

Our food and consumer safety reference materials help agricultural and food safety laboratories worldwide monitor and assess the state of food and agriculture. Inorganic standards range from elemental impurities and inorganic species to macronutrients and packaging contaminants. Our organic standards, designed around analytical needs and international methodologies, range from pesticide testing to target fragrance and flavor compounds. We also have food and consumer analytical materials that include microbiological standards for laboratories performing QA/QC testing using positive live controls. ZeptoMetrix food and consumer analytical reference materials are certified for multiple methods (e.g., FDA, USDA, AOAC, ASTM, ATF, etc.).
