Abstract
The invention relates to a method for analysing hydrocarbons, with the implementation of a gas chromatography separation according to a first controlled temperature profile, to separate a sample into a plurality of analytes and the detection of at least one of said analytes by measurement of a variation of the resonance frequency of at least one resonator of nano-electromechanical system (NEMS) type covered with a functional layer made to vibrate at the resonance frequency thereof, under the effect of an adsorption or desorption of the analyte by the functional layer, the resonator being subjected to a second controlled temperature profile, lower than the first profile.
