1.4.8 Absorbance Module
The Absorbance Module measures the optical density (OD) of the final reaction mixture in
each microplate well. The wavelength that is used and the wavelength(s) at which the optical
density is measured are specified during assay definition.
During operation, each microplate is automatically transferred to the absorbance module at
the appropriate time. The optical densities of the wells specified during assay definition are
read, the various calculations (for example, Blanking, QC Raw Data, Threshold or Curve
Fitting) are applied, and the calculated results for the microplate are reported.
The location of the absorbance module is shown in Figure 1-11.
