To obtain accurate and reliable DLS measurements in catalysis, consider the following optimization tips:
Sample Preparation: Ensure that the sample is well-dispersed and free of dust or large aggregates that could skew the measurements. Concentration: Optimize the concentration of the sample to avoid multiple scattering and ensure accurate size determination. Measurement Conditions: Perform measurements at controlled temperature and pH to maintain the stability of the sample. Data Analysis: Use appropriate data analysis methods to accurately interpret the correlation function and derive particle sizes.
