Q.50
Ideal range of absorbance for accepting data from spectrophotometer is
- Photometric Accuracy & Beer-Lambert Law: In UV-Vis spectrophotometry, photometric accuracy and reproducibility depend on maintaining transmission within the optimal linear dynamic range where the relative error in concentration measurement is minimized.
- Ideal Absorbance Range: The optimal absorbance range for analytical measurement is 0.2 to 0.8 (corresponding to ~15% to 65% transmittance), where spectrophotometric detector noise and stray light errors are minimal. (Correct answer: Option 4)
