	CLICK HERE FOR CONSUMER DATA REPORTS Testing Services NDI, through its certified and accredited reference laboratory partners, tests omega-3 and whole fish products for PCB, Mercury, Heavy Metals, and Oxidation levels in accordance with Council for Responsible Nutrition’s voluntary monograph on omega-3 products and safety standards for human consumption. Dioxin and Furan levels are tested against the World Health Organization’s standard and omega-3 concentration is tested and compared with the product label claim. PCB, Dioxin and Furan levels are tested using gas chromatography mass spectrometry at a detection limit of parts per trillion. Mercury is tested using cold vapor atomic absorption spectroscopy at a detection limit of parts per billion. Omega-3 content is tested using gas chromatography advanced capillary techniques as a percentage of weight. Heavy metals are prepared by microwave assisted digestion in nitric acid, the resulting solutions are diluted to volume for trace element analysis by inductively coupled plasma mass spectrometry and inductively coupled optical emission spectroscopy. Arsenic and Nickel are tested in parts per million, Lead and Nickel are tested in parts per billion. Oxidation testing is conducted using a titration method for peroxide and uv-visible spectrophotometer for p-anisidine under numbered official AOCS methods Cd 8-53 for peroxide and Cd 18-90 for p-anisidine respectively. Although the standard detection limit expressed for each category is set by the governing organization, the IFOS program tests the products at far lower levels of detection in most categories, based on the most advanced analysis technology platforms available. As the sophistication of the instrumentation increases, the IFOS program will continue to update the testing regiment to ensure it is on the leading edge of science.
