Calibration of the Instrument for
Measurement Analysis

In the analysis mode, the Orion 2295 Phosphate Analyzer measures the absorbance of light
through the sample, and compares the result with the absorbance of light through a standard
solution of known concentration.

Theory of Calibration

Using two known standards, one of low concentration and the other of high concentration, the
absorbance for each concentration is measured and the slope and intercept are calculated from
the calibration curve as shown below:

The Measured Absorbance is the result absorbance after subtracting the Blank Absorbance.
