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 agro-food products (raw, processed, canned, etc.), 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).  

​​​​​​​LEAF also operates FAFS laboratories. In line with the mission and vision of the faculty, laboratories at FAFS aim to provide hands-on agricultural experience and constitute a suitable background for scientists and students to implement proper lab diagnostics and assessment techniques. FAFS labs record of excell​ence has positioned them to rank among the top institutions in Lebanon and the region across multiple disciplines of sustainable plant and animal health and production, human nutrition and dietetics, Food safety and security, landscape design, environment, community and rural development and others. FAFS labs provide state-of-the-art laboratory support to further broaden the collaboration with the industry, public and private sector in order to improve the wellbeing of people in Lebanon and the region, educate future scientists through hands-on experience, and address emerging problems facing agriculture and food in Lebanon and the region, as well as satisfy the needs to tackle novel research issues imposed by recent challenges such as global warming, water scarcity, emergence of zoonoses and species-specific infections, etc.​​​​

The laboratory provides testing services on numerous sample matrices, including the following: 

  • Food
