Hexafluoropropane extinguishant recognition detection method

The invention discloses a hexafluopropane extinguishant recognition detection method. The method comprises the steps of acquiring a near infrared spectrum of a standard sample and a near infrared spectrum of a to-be-detected sample, primarily judging whether an unknown sample is hexafluoropropane extinguishant or not by virtue of the comparison of absorption peaks of the near infrared spectrums with wave numbers being 4084.5cm , 4234.9cm , 4335.2cm , 4435.5cm , 5797.0cm , 5901.1cm and 6028.4cm ; selecting a specific wave number range, establishing a detection model of the hexafluoropropane extinguishant, and accurately recognizing the extinguishant by utilizing the established model. A purpose of accurately recognizing whether the unknown sample is the hexafluoropropane extinguishant is realized by virtue of the analysis modeling of the chemometrics. According to the method, the operation is simple, rapid analysis is realized, and the analysis cost is low.
