4 OVERVIEW Technical description of OVIVO urea analyzer The working principle of the system is based on a chromatographic separation by combination (coupling) of three specific properties of urea. 1. The first property is related to the non-ionic nature of urea. This is quite unique, as N-compounds are generally ionic, either anionic (e.g. nitrate) or cationic (e.g. amines). Thus, urea will have shorter retention time, if separated on a cation exchange liquid chromatographic column in respect to cationic compounds, or longer retention times in respect to an anionic exchange chromatographic column. Therefore, it is possible to isolate urea from other N-compounds by liquid chromatographic methods. 2. The oxidation behavior of urea: After exposition to short wave UV-light, urea will first undergo a disproportionation reaction, the breakdown to carbon dioxide and ammonium. If UV-wavelength and intensity is sufficient then ammonium will rapidly be oxidized to nitrite and then nitrate. Other organic compounds will be converted to carbon dioxide, organic N-compounds will be converted to carbon dioxide and nitrate. Heterocyclic compounds will also produce elemental nitrogen if nitrogen is present in a vicinal fashion. 3. The high molar extinction coefficient of nitrate at wavelengths < 230 nm. Due to this, nitrate can be detected and quantified at very low concentrations by spectrometric methods. Other salts found in natural or technical waters do not have this property; nitrate is almost (except e.g. bromine and iodine) the only species that is detected at short wave UV. Flow diagram of the OVIVO urea analyzer: The water sample passes through a multiplexer into the actual analyzer. The mobile phase (a salt buffer) is pre-cleaned by a special designed oxidation reactor (DOCOX). Then, a defined volume of aqueous sample, picked up by a loop, is inserted into the continuous stream of the mobile phase. It is thereafter fed to a HPLC pump and then to a chromatographic column in which urea is separated from other N-species, like nitrate and ammonium. After leaving the column the solution is fed to a short-wave UVoxidation lamp (DONOX) in which urea is converted to nitrate, while nitrate remains unaffected and ammonium is converted to nitrate. Thereafter the liquid is fed to a UVdetector (220 nm) and all nitrate is quantified. All species elute according to their specific retention times and retention time is used for identification while peak area units are used for quantification. Analyzer UREA 1601 Vers Page 4 of 12
