New Cod Liver Oil Interlab Study Results

Recently, Cambridge Isotope Laboratories , Inc. organized an International Interlaboratory study on two cod liver oil reference materials, one spiked with known amounts of chlorinated dioxins, furans, and PCBs and one clean standard. Results from participating laboratories have been received and processed, and consensus values for several classes of environmental pollutants have been assigned. Click here for full article.


  • New Cod Liver Oil Interlab Study Results
  • “High Purity” PCB Standards from CIL
  • Plasticizers in Food Are Now Substances of Higher Concern

Adulteration of food and feed products around the world has led to increased scrutiny of consumable goods. CIL manufactures a wide array of analytical standards for many food and feed pollutants such as PCBs, pesticides, PAHs and more. Newer developments include standards for interesting adulterants such as melamine, acrylamide, bisphenol A, diethylene glycol, and phthalate esters, allowing highly accurate quantitative analysis of these compounds.
