A spectrophotometer is a relatively simple piece of equipment composed of:
Signal amplifier-Concentration counter
So the absorbance of radiation is proportionate of the concentration of the compound we want to measure (for the specified compound) and the distance that the light has to travel
Sample in the quvette
NO3- NO2- PO4-3
Transmitted light intensity
Initial light intensity
