Providing analytical services:

The Laboratory of Analytical Chemistry (L.A.C) of the Department of Chemistry of the National and Kapodistrian University of Athens (N.K.U.A) has a 50-year experience in developing and applying innovative analytical methods and techniques in a variety of research fields, including Food Chemistry as well as Environmental, Pharmaceutical and Industrial Chemistry. L.A.C has a long-term collaboration with public services (Ministry of Rural Development and Food, EFET, among others) and also with private food companies dominating in Greek market (JIOTIS SA, DELTA, NIREUS, among others) providing specialized services in food analysis.

L.A.C. is an accredited laboratory by E.S.Y.D for the determination of veterinary drugs and heavy metals in food matrices (certification number 636). Since 2016, L.A.C. has been assigned as the National Reference Laboratory (NRL) for the determination of coccidiostats in animal tissue and egg samples. Additionally, the successful participation of LAC in several proficiency test schemes for the determination of veterinary residues, metals, total and inorganic arsenic, preservatives and colorings in foodstuffs, ensures the Laboratory’s reliability.
