A method and a system for detecting the presence of propellant gas in a gaseous sample exploit laser light especially in the 3.30-3.5 &#x3bc;m range. The propellant can be propane, n-butane, i-butane, dimethyl ether, methyl ethyl ether, HFA 134a, HFA 227, or any other propellant exhibiting absorption in the requisite wavelength range. The presence of the application of this method in leak testing of propellant-containing containers such as aerosols or fuel canisters, permits high-speed, high accuracy leak detection capable of replacing existing testing methods.
