Determination of nitrogen and acrylic / styrene components in nitrocellulose systems by UATR and NIRA infrared techniques

Nitrocellulose (NC) is a polymer of great interest in the aerospace and paint/coating fields. However, there are gaps regarding quantitative analysis. Fast and accurate methodologies for the quality control of raw materials are limited. In this context, the determination of the nitrogen content in N...
