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).
