Abstract
A method and device for fluorimetric determination of a biological, chemical or physical parameter of a sample utilize at least two different luminescent materials, the first of which is sensitive to the parameter, at least with respect to luminescence intensity, and the second of which is insensitive to the parameter, at least with respect to luminescence intensity and decay time. The luminescent materials have different decay times. The time- or phase behaviour of the resulting luminescence response is used to form a reference value for determination of a parameter.
