Chemical applications have utilized NIR for many years due to the many routine measurements that have been successfully developed for the chemical industry. NIR is extremely sensitive to the O-H absorbance and moisture determination is therefore a common application.

Reaction monitoring and end point determination are good applications for organic chemistry reactions and processes, because NIR is also sensitive to N-H, C-H and S-H bond absorbance. Many applications that have historically been measured with physical property testing, like viscosity, may be measured with NIR if it is dependent on an intrinsic chemical characteristic, such as chain length or cross linking.

Common chemical analytes include: acid value, hydroxyl number, adhesive content, antioxidant and UV inhibitor content, cure, melt index, HDPE/LDPE, melamine content, plastic identification, polymer analysis, alcohol detection/analysis and residual solvent detection.
