It is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution.
SPECTROPHOTOMETRY
Give one application of spectrophotometry
•Forensic sciences
• Molecular biology
• In disease diagnosis/ pathological states (changes)
• Blood (the blood plasma, and the formed elements
• To identify and quantify biological molecules
• Measurement of concentration
• Detection of impurities
• Elucidation of the structure of organic compounds
• Chemical kinetics
It is a measurement of light that absorb by the sample.
