PrinCiPleS oF MeASUreMent
A number of tests run on a spectrophotometer involve an active ingredient. On addition of this active
ingredient, the absorbance or the transmittance of the sample, will be seen to either increase or
decrease. The absorbance or transmittance is recorded at regular intervals at a preset wavelength for a
set time.
A graph is then plotted to show how the absorbance or transmittance changes over time. From the
graph, the concentration of the sample can be calculated. This mode is ideal for continuous monitoring
as well as the calculation of concentration in enzyme activity studies, with calibration possible against a
standard or known factor.
