An instrument is characterised by operational feedback between the signal at the exit of amplifier and speed of feeding of analysed solution. The feedback operates with information, it is calculated by formulae under logic conditions. Due that the instrument self-retunes during analysis every sample in optimal condition for analysis this sample and allowes to analyse solutions from detection limits to tens gram/litre with one calibration by one standard. Concentration is calculated by formula <CHEM> where A - signal by amplifier, nu - friequency or function that is proportional to feeding. The three-parameter method operates with calibration surface as shown at Figure. One surface corresponds to one set of calibration conditions.
