Who is it for

This module is relevant to quality control and quality assurance team members who conduct and evaluate particle size data

Why it matters

Pharmaceutical raw materials are processed through grinding, sieving, micronizing and blending operations. Each of these operations affect particle size which is critical to final drug product quality. Finer particles, dissolve quicker, and the speed of dissolution has direct effects on bioavailability and effectiveness of a drug. Understanding the theory and applications of particle size determination is crucial for analysts.
