Purpose:

To explore the reasons why measurement instruments in the field may deviate from the linearity alleged by the Beer-Lambert law

To introduce a university textbook dealing with inter alia:

External Calibration

Creating a Calibration Curve

Limits to Beer's law

No longer linear when the molar absorptivities differ

Instrumental Deviations from Beer-Lambert law

Polychromatic Radiation rather than Monochromatic IR
