Abstract: A refrigerant analyzer (10) including a sample chamber (12) including, a proximal end (14), a distal end (16), an inlet port (18) and an outlet port (20), an infrared lamp (22) disposed adjacent to the proximal end (14) of the sample chamber (12), an optical filter (24) disposed adjacent to the distal end (16) of the sample chamber (12), and a non-dispersive infrared sensor (26) disposed adjacent to the optical filter (24); wherein the optical filter (24) is configured to transmit a wavelength less than or equal to approximately 15,500 nanometers. A method of detecting a counterfeit refrigerant within a system utilizing a refrigerant analyzer (10), the method including the steps: (a) connecting a refrigerant container (52) to the refrigerant analyzer, (b) operating the infrared lamp (22) and the non-dispersive infrared sensor (26) for a duration of time, and c) operating the non-dispersive infrared sensor (26) to detect a wavelength less than or equal to approximately 15,500 nanometers.
