ABSTRACT:
A method of determining a concentration CM of a component in a sample by measuring a light transmissivity TM of the sample. First, light transmissivities T.sub.C1 and T.sub.C2 of a first standard and a second standard respectively having known concentrations C1 and C2 of the component is measured. Then a correction factor K3 is calculated according to the following three equations:
