What are the most common mistakes made by scientists using technologies such as laser diffraction and dynamic light scattering to measure particle size?
How can these mistakes be avoided?
How can some of the most common causes of poor reproducibility be used to create experiments to validate your method?
This webinar will focus on the issues of unstable samples, poor backgrounds and poor analysis choices. None of these issues are complex, and awareness of potential issues and how to avoid them will result in significant improvements in the quality of your measurements.
