Analytical Services

​​​​​​​​​​​​​​​​​​The Environment  Laboratory (EVL)- 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. EVL -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. EVL-LEAF services also cover pharmaceutical products,  occupational and public health research and diagnostic medical services such as organic acids, trace and heavy metals, tobacco & 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).
