Heavy metals laboratory
Heavy metals laboratory, one the laboratory services of the Department of Social and Environmental Medicine, Faculty of Tropical Medicine, Mahidol University. We provide the analysis of heavy metals in environmental and biological samples by Flame Atomic Absorption (FAA) and Graphite Furnace Atomic Absorption (GFAA) Spectrophotometer. Productivity, accuracy and precision of determination at low levels provide methodology needed for research and quality control.
