Analysis of fat soluble vitamins in food samples and amino acid sequencing in protein
The Canadian Nutrient File team, within the Nutrition Research Division, manages the Sampling and Nutrient Analysis Program for Canada (SNAP-CAN), which collects samples of priority foods and analyzes nutrient profiles for two food categories per year specifically to meet program needs of the Food Directorate of Health Canada (i.e. not a ‘fee-for- service’ laboratory).
Access to the specified equipment to qualified analysts.
Analysis of fat soluble vitamins in food samples by Ultra-Performance Liquid Chromatography coupled to Photodiode Array and Fluorescence Detection Tandem Mass Spectrometry (UPLC-PDA-FLR-MS/MS) Waters ACQUITY UPLC-XEVO Triple Quadruple Mass Spectrometer (UPLC-XEVO TQ-MS).
The laboratory also has equipment for amino acid sequencing in protein by sequentially cleaving amino acids from the N-terminus of a pure protein or peptide.
