Pickering Labs was extremely excited to start hitting the trade-show circuit again, after an enduring a LONG absence since Pittcon 2020. Our Customer Service Manager, Rudy Suez, and Technical Support Chemist, David Mazawa, attended the NEMC Conference in Bellevue, WA in early August. Our Senior Research Chemist, Maria Ofitserova, and Sales Manager, Kevin McKeown, attended the AOAC annual show in Boston in late August. It was a joy to see our customers face-to-face (mask-to-mask?!) again and do a reintroduction of our Onyx PCX instrument. Upcoming shows where you can see Pickering Labs include ACIL in Long Beach, CA in early October and AATCC (American Association of Textile Chemists and Colorists) in Raleigh, NC in mid-November.

New Method Abstract MA 249

ma_249Analysis of Mycotoxins is an important part of food and feed safety.  As regulations tighten laboratories all around the world expand their testing capabilities to include analysis for different types of toxic fungi metabolites. Pickering Laboratories has a diverse line of products designed for Mycotoxins analysis, including Pinnacle PCX post-column derivatization system, UVE photochemical reactor and immumoaffinity columns. We also developed several methods for single families of Mycotoxins as well as multi-residue protocols.

Our new Method Abstract MA249 describes fast and sensitive method for analysis of Fumonisins FB1, FB2 and FB3. Fumonisins are derivitized with OPA reagent and detected using Fluorescence detector. HPLC and post-column conditions of this method are aligned with a method being considered by Chinese National Food Safety Standards as new official method for Fumonisins in food.

Pickering at AOAC International in Philadelphia

By Mike Gottschalk, Marketing Manager

It was the 125th Anniversary of the AOAC in Philadelphia, Pennsylvania and this annual meeting was especially exciting with the anniversary celebrations.

At the Vendor exhibition we highlighted our Mycotoxin and GPC Sample-Cleanup products lines to expand our offering of the post-column derivatization products we are most known for.

The Scientific sessions also reflected growing interest in the analysis of Mycotoxins as well as Paralytic Shell Fish Toxins and a broad range of analytical instrumentation and techniques.

Dr. Pickering, Dr. Ofitserova, Dr. Nerkar, Dr. TormaWe brought a large contingency of personnel including Dr. Pickering, Dr. Ofitserova, Dr. Nerkar, Dr. Torma to accept the AOAC’s Single Laboratory Validation of the Year Award for our Multi-residue Mycotoxin Analysis. The paper, titled “Multi-residue Mycotoxin Analysis in Corn Grain by Column High-Performance Liquid Chromatography with Post-column Photochemical and Chemical Derivatization: Single-Laboratory Validation” was also published in the Journal of AOAC International Vol. 92, No. 1, 2009.
