Analytical Services

LEAF is furnished with state- of- the- art equipment for the extraction/digestion, analysis and identification of a vast array of  inorganic and organic chemicals. LEAF applications ranges from identification of contaminants in different environmental matrices (e.g. water, waste water, soil, compost.), food and agri food products (raw, processed and canned), and non-edible oil analysis (such as gasoline, diesel and industrial oil), to food chemistry and microbiology such as nutritional labeling, pesticides residues, heavy metals, colorants, allergens, and aflatoxins. LEAF services also cover pharmaceutical products,  occupational and public health research and diagnostic medical services such as organic acids, trace and heavy metals, tobacco metabolites (nicotine, cotinine, 1-HOP) and exposure to specific organic pollutants and its metabolites in biological specimens (hair, semen, blood, urine, teeth and body fluids).
