Simultaneous determination of concentration of several components or multiple component system involves filling and tempering measuring cuvette with system, subjecting to microwave impulse, and further processing

摘要

Process for simultaneously determining the concentration of several components or a multiple component system involves filling and tempering a measuring cuvette; subjecting to microwave impulse; measuring the temperature progression and/or damping the medium; repeating using a second microwave impulse P2; acquiring calibration data from a known composition; and calculating the concentration. Process for simultaneously determining the concentration of several components or a multiple component system involves filling and tempering a measuring cuvette with the multiple component system; subjecting to a microwave impulse P1; measuring the temperature progression and/or damping the medium; repeating the second and third steps using a second microwave impulse P2; acquiring calibration data for concentration determination by measuring a liquid or gaseous multiple component system of known composition using the previous steps; and calculating the concentration of the individual components of the multiple component system with evaluation algorithms using acquired temperature/damping dependencies and the calibration data. Preferred Features: The multiple component system is a system with an aqueous matrix, e.g. cleaning agent or lubricant bath, a printing ink, a slip, an electro-immersion lacquer, a dispersion ink or liquid foodstuff, such as a drink, e.g. fruit drink; or is a system with a non-aqueous matrix, e.g. a drawing oil, a lubricant, a gear or engine oil, or a coolant. The measurement of the microwaves is carried out in the region of 0.8-10 GHz.
