Co-Chair : Ping Wan, Indiana State Chemist Co-Chair : Jon Wong, U.S. Food and Drug Administration Paul Yang, Ontario Ministry of the Environment Multiresidue Analysis of Polar Pesticides Using HILIC Separation and Tandem Mass Spectrometry. Grace Bandong, Eurofins Central Analytical Laboratories Pesticide Residues in Essential Oils: Risks, Occurrences and Practical Approaches to the Analysis in a Quality Control Environment Jing Qiu, Chinese Academy of Agricultural Sciences Multi-Residue Screening and Confirmation of Pesticides in Animal Tissues with Fast Sample Preparation TDRM Symposium: The Importance of Public Private Partnerships in the Development of Reference Materials Reference materials, both certified and non-certified play an essential role in laboratory testing, demonstrating the proper functioning of analytical methodology and ensuring prod- uct quality and safety. However, with a world of varied and complex matrices, how do reference material producers select projects and acquire candidate reference materials? Through interactions with industry, reference material producers are able to develop an understanding of the most significant needs of a particular industry sector. Further partnering with industry allows for sharing of materials and methods that are critical steps in the characterization of a candidate reference materials. The proper use of public/private partnerships allows for targeted and some- what accelerated reference material production, the speakers in this session will describe examples of successful public private partnerships and will finish with a brief roundtable discussion. Co-Chair : Catherine Rimmer, U.S. National Institute of Standards and Technology Co-Chair : Charles Barber, U.S. National Institute of Standards and Technology Holly Johnson, American Herbal Products Association Botanical Reference Materials for Quality Assurance and Regulatory Compliance in Dietary Supplements Chemical Risk Assessment of Ingredients Katarzyna Banaszewski, NOW Foods

10:15 am – 11:45 am Latest Developments in Gluten Analysis

Looking back over the past two decades, the story of gluten measurement was driven by the intertwined interests of celiac patients and the gluten-free industry that need to follow regula- tions. Development of analytical methods brought both interests step by step together. Sensitive gluten estimation methods demonstrating high accuracy and low variability were warranted to meet the demand of gluten-free foods. Though many methods are available today, considerable variation is observed between their gluten measurements arising from differences in method parameters and food properties. This symposium will present new analytical developments in the ELISA and mass spectrometry area as well as provide insights on the impact of sampling and food matrix on method performance. Co-Chair : Girdhari Sharma, U.S. Food and Drug Administration Co-Chair : Carmen Diaz-Amigo, FOCOS Food Consulting Strategically Thomas Weiss, R-Biopharm AG Validation of an ELISA for Total Gluten Determination Michelle Colgrave, CSIRO Agriculture and Food An Update on Gluten Analysis by LC-MS/MS Paul Wehling, Medallion Laboratories / General Mills Appropriate Sampling Can Help Improve Decision Making in Gluten-Free Systems
