TAN, JING – ABBOTT NUTRITION I have acquired strong knowledge and skill set on food contaminants analysis from my 13+ year of academic and  industrial working experience. During my tenure in Abbott Nutrition, I have done various contaminants analyses  including bisphenol A and I am well‐versed in sample preparation and instrument analysis.  TUZIMSKI, TOMASZ – MEDICAL UNIVERSITY IN LUBLIN My scientific interest includes the theory and application of liquid chromatography, taking into considerations  optimisation of chromatographic systems for separation and quantitative analysis of analytes in multicomponent  mixtures of xenobiotics and unknown compounds residue in food, environmental and biological samples. The  main of research interest during last four years (2013‐2017) was to develop analytical methods for xenobiotics  analysis in food products of plant and animal origin by high performance liquid chromatography (HPLC‐DAD, HPLC‐ MS and/or HPLC‐MS/MS). In order to accomplish this goal, optimization experiments were conducted for, both,  the chromatographic conditions of separation and quantitative analysis, as well as sample preparation approach  for efficient isolation of the analytes (eg., pesticides, 5‐nitroimidazoles (NDZs), sulfonated azo dyes, drugs,  bisphenol A and its metabolites) form different food samples and subsequent extract clean‐up. Sample  preparation procedures for the analysis of various commodities, including sunflower seeds, edible oils, milk, soya  milk, wines, different beverages, candies and caviar/fish roe, were developed by the optimization of the  conditions of analytes isolation from complex matrices and extracts clean‐up. For that purpose, different  extraction and clean‐up techniques were used, mainly QuEChERS (quick, easy, cheap, effective, rugged and safe),  ultrasound assisted extraction (UAE), solid‐phase extraction (SPE), dispersive‐SPE (d‐SPE) and matrix solid‐phase  dispersion (MSPD).  SUDHAKAR YADLAPALLI ‐ FIRST SOURCE LABORATORY SOLUTIONS  Having knowledge and analytical experience in analysis of Bisphenol in water samples as per EPA.  Contributed in  collaborative study toward method to detect agricultural residues at sub –parts–per‐billon levels in Soft drinks  published as AOAC Official method 2007.08, First Action.
