Portable refrigerant identification by near infrared spectrophotometry.

Author(s) : SNYDER S., WILLIS J., TOBIAS R., MANZ K.

Summary

Near infrared spectrophotometric analysis has many advantages over physical property investigations for refrigerant type identification. Two facets where near infrared analysis excels are the accuracy in detecting mixtures of refrigerants and the number of refrigerants capable of being identified. Near infrared provides a fingerprint of the substance analyzed which gives a much more accurate representation compared to a single physical property measurement. The sophisticated analysis of near infrared can be transformed for field use so that air conditioning and refrigeration technicians can deal with the numerous types of refrigerant in the market today and that will emerge in the future. Patent applications have been filed on the near infrared technology and subsequent use in portable refrigerant identification.
