How do you operate a benchtop spectrophotometer? Give its principle and distinguish the colour characteristics of a specific polymer with a known standard before full-scale production.

Question

Accepted Answer

Operating a benchtop spectrophotometer involves understanding its principle, calibrating with known standards, and comparing color characteristics of polymers.

Understand the principle of spectrophotometry - measures the intensity of light at different wavelengths
Calibrate the spectrophotometer using known standards to ensure accurate readings
Prepare samples of the specific polymer and the known standard for comparison
Measure the color characteristics of both samples using the spectrophotometer
Compare the color data obtained from the polymer with the known standard to ensure consistency before full-scale production
