Abstract: The device (1) comprises first and second atomizing units (2, 2'), which comprise a liquid inlet (21), a gas inlet and a connector for the mixing chamber, so that liquid essence and -reference comprising essence, reference material, water and/or ethanol are supplied into the atomizing units by using the liquid inlet and an inert gas is supplied into the atomizing units by using the gas inlet, where the atomizing units are suited to atomize the liquid and the inert gas to aerosol and then to supply into the mixing chamber, and a mixing chamber (3), which comprises an evaporation device. The device (1) comprises first and second atomizing units (2, 2'), which comprise a liquid inlet (21), a gas inlet and a connector for the mixing chamber, so that liquid essence and reference to be prepared comprising essence, reference material, water and/or ethanol is supplied into the atomizing units by using the liquid inlet and an inert gas is supplied into the atomizing units by using the gas inlet, where the atomizing units are suited to atomize the liquid and the inert gas to aerosol and then to supply into the mixing chamber, a mixing chamber (3), which comprises an evaporation device and a connector for the separation chamber, is arranged after the atomizing units and is then connected, so that aerosols formed by the atomizing units are separately supplied into the mixing chamber, where the evaporation device is suited to transport a part or ethanol of the supplied aerosols partially or completely into a gas phase, a separation chamber (4), which comprises a gas outlet and a connector for the condensation chamber, is arranged after the mixing chamber and is then connected, so that the ethanol transported in the gas phase and the remaining aerosols are supplied into the separation chamber and a part or the ethanol gas-phase is removed from the device by the gas outlet, a condensation chamber (5), which comprises a liquid outlet and a condensation device, is arranged after the separation chamber and is then connected, so that the remaining aerosols in the separation chamber is supplied into the condensation chamber after partially or completely removing the ethanol-gas phase, where the condensation device is suited to partially or completely condense the supplied aerosols and condensate is removed from the condensate chamber by the liquid outlet, and a liquid chromatographic system connected with the liquid inlet of the first atomizing unit, so that eluate obtained by the liquid chromatographic system is supplied as the essence by the liquid inlet of the atomizing unit. The first and/or second atomizing units are operated at 20-25[deg] C. The gas inlet of the atomizing units comprises a regulator for adjusting an operating pressure in the atomizing units, where the operating pressure is 3 bar. The liquid inlet of the atomizing units comprises a controller for adjusting a feeding speed of the liquid into the atomizing units, where the feeding speed is 3 ml/minutes. A detector is arranged between the liquid chromatographic system and the first atomizing unit for detecting the essence in the eluate. Independent claims are included for: (1) a method for producing a liquid essence flavor condensate for sensory evaluation of reinforcing or reducing essence properties by a test person; (2) a method for sensory evaluation of reinforcing or reducing flavor properties of the essence; and (3) a method for diluting a liquid essence to be prepared.
