Application Note: Opadry Verification Using a Handheld Raman Analyzer
1 December 2017
Pharmaceutical companies that manufacture tablets, capsules and other solid dosage forms use a film coating on their products to differentiate visual appearance, to improve the ability to swallow and to mask objectionable tastes or odors. Film coatings also reduce tablet breakage and chipping as well as provide protection from light, moisture and environmental gases. In this application note, a principal component analysis method was used to identify the pigment in the film coatings.
