overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Spectrophotometry is an analytical technique used to measure the intensity of light absorbed by a sample at specific wavelengths. It is widely employed in chemical, biological, and environmental sciences to quantify the concentration of substances, analyze molecular interactions, and study absorption spectra. This method leverages the principles of light absorption to provide precise and rapid measurements, making it a fundamental tool in laboratory analysis.
