Over the last twenty years or so, laser diffraction has emerged as a widely accepted technique for particle size analysis across different segments. The various advantages of the technique like wide dynamic range, high sample throughput, the robustness of results and regulatory acceptancy make it popular in both the R+D environment and QC departments.

This webinar is part of the laser diffraction analysis webinar series. In this webinar, Application Specialist for Malvern Panalytical, Tamal, will cover features available in the Mastersizer 3000 software, utility tools that can be helpful in both R+D environment and quality control. He will will discuss about data analysis with reference to the pharmaceuticals industry among other industries including battery, specialty chemicals and more.
