Description
Calcium is also measured photometrically with reagents. Photometric analysis is based on the Beer-Lambert principle of absorbance. Photometric analysis products include benchtop photometers, and spectrophotometers. Photometric methods include reagent chemistries based on the Calmagite method found in the Standard Methods for the Examination of Water and Wastewater.
