The measurement was performed and the instrument is ready for the next measurement. In addition, the device can operate in automatic mode, then the signals arrive at the corresponding valves of the metering devices and mixers in accordance with the device operation. In a cylindrical flow chamber, the volume of the water-oil mixture (1 l) is prepared. Mixing elements disperse the water-oil mixture, in which all oil and oil products are transferred to the solvent, and then in the same construction (the cylindrical chamber is separated. The gravity separation chamber provides a reliable supply of solvent for further preparation for analysis and draining an excess for regeneration A mixer was added to dilute the dose of concentrated solvent. If, for example, there is a low concentration (15 mn), then 100 cm CC1 is fed into the I l mixture, and The 150 ml enena concentration goes directly through the dispenser 11 to the mixer and then without dilution further to the IR photometer for analysis.
