Abstract (en)

[origin: GB2335037A] A method of measuring a concentration dependent parameter of a sample, e.g. concentration itself, comprises:- making a first measurement at a first concentration, diluting the sample and making a second measurement at a second concentration, analysing first and second measurements and comparing the result with a predetermined expected behaviour, determining the value of the parameter if the expected result is achieved or, repeating the step of diluting the sample and making a further measurement at the further concentration, analysing the further measurement with respect to at least one of the earlier measurements and comparing the result with the predetermined expected behaviour and repeating the dilution measurement and analysis steps until the result agrees with the predetermined expected behaviour, such that the value of the parameter can be determined. A sample diluter and a sample measuring system, e.g. an impedance particle sizing system, are also disclosed.
