The solid trace in Fig. 7a shows the measured absorbance in holder 1 for a cuvette containing a suspension of microalgae in a growth medium. The dotted trace in Fig. 7a shows the measured absorbance when the cuvette is transferred to holder 2. The solid trace in Fig. 7b shows the molecular absorption coefficient obtained using Eq. (8), Eq. (9) and the data in Fig. 7a. The solid trace in Fig. 7c shows the apparent scattering absorption coefficient obtained using Eq. (8), Eq. (9) and the data in Fig. 7a.
