Who is it for

Personnel in production, analytical quality, including quality control and quality assurance who use this technique should complete this module.

Why it matters

Each pure sample has a constant, and unique refractive index that can be determined with great accuracy. Therefore, refractive index is frequently used as an identification tool to determine the purity of samples. Understanding the science of refraction can enable analysts to perform QC experiments correctly and get to the root cause of any errors.
