NIRS is uniquely suited for quantitative analysis of polymers due to the inherent benefits of this method:
- no sample preparation required
- method is non-destructive
- results in a matter of seconds
NIRS has been successfully used to analyze other copolymers such as ethylene/propylene, styrene/butadiene, and butylene/terephtalate. Polymer additives such as antioxidants, stabilizers, and slip agents are also being monitored by NIR in pelletized samples.
