Measurement is the process of determining a correct value of a measurand; definition of the measurand is decisive for an expedient choice of a measurement method. The result of a measurement refers in principle only to the amount of substance actually contributing to the analytical signal. An appropriate definition of the measurand, however, must include a specification of the entire system, for which the result of the measurement is required to apply, i.e., which it is supposed to represent.
