Pickering Laboratories - Analysis of Mycotoxins in Hemp and Hemp- Containing Edible Products

Pickering Laboratories developed an easy and sensitive method to analyze aflatoxins B1, B2, G1, G2, and ochratoxin A in hemp and hemp-containing edible products. Mycotoxins are isolated using immunoaffinity clean-up columns and analyzed with fluorescence detection. To increase sensitivity of aflatoxins B1 and G1, an in-line photochemical reactor (UVETM) is installed before the detector. This method utilizes standard HPLC equipment and allows laboratories to easily determine these mycotoxins at low ppb levels.

Analysis of Amino Acids in Oxidized and Unoxidized Feed Samples

Commission Regulation (EC) No 152-2009 published in the official Journal of European Union laid down the methods of sampling and analysis for the official control of feed. The Regulation describes methods of analysis to control the composition of feed materials and compound feed products. Establishing the amino acids profile is an important way to control quality and nutritional value of feeds.
