The laboratory is specialised for determination of composition, properties and contamination of waters, soils, and bottom sediments. They are ohysical-chemical analytical tests including sampling operations according to corresponding standards and binding methods. Laboratory tests and analyses relate to the following: waters (fresh/drinking, surface, ground, mineral, table and healing, swimming-pool, and waste water), muds, solis, earths and minerals, selected industrial products and chemicals, and biomass. In the laboratory we utilise mainly analytical methods carried out by the following devices: Thermospectronic Genesys 8 Spectrophotometer, HANNA HI 83215 photometer for nutrients determination, MERCK photometer with reactor for the determination of chemical oxygen consumption, several fixed and mobile conductometers and pH meters including ion selective electrodes, mobile refractometer, video microscope, etc.
