1. Setup of the

First, turn on your Cary 60 UV-Vis Spectrophotometer. Let it warm up for at least 30 minutes. Then initiate the operating software on the computer (Cary WinUV), making sure that the lamps and optics have reach a stable condition.

2. Baseline Measurement

Position a blank reference cuvette filled with the corresponding blank solution (solvent, in this case) within the sample compartment. A baseline scan is necessary to automatically factor out background absorbance values prior to actual testing with a sample.

3. Sample Preparation:

Prepare samples in clean matching cuvettes with accurate volume and optical clarity. Prevent bubble formation and fingerprints to avoid spectral artifacts.

4. Measurement

Load samples and specify a desired wavelength region (e.g., 200-800 nm), or specific monitoring wavelengths. 5. Data Handling & Cleanup: Save all spectral data. Also, remove all cuvettes from the instrument. Clean all cuvettes thoroughly.
