Zusammenfassung:	A method and a system for classifying at least one individual gas compound from a plurality of leaked gases in a specified field of view are provided herein. The method may include the following steps: generating, by a cryogenically cooled detector and using a first of at least n filters, multiple spectral band images of the specified view in spectral bands coinciding with said leaking gases spectral bands in which said leaking gases emit and absorb electromagnetic radiation; calculating from the images, the relative absorption response of said gases in each of said filters, respectively; calculating a set of predetermined coefficients; normalizing said relative absorption responses to the sum of relative responses of said filters; and calculating the weighted average molecular mass of said gas compound of said leaking gases.
