Abrégé
(EN)
A portable Raman spectroscopy instrument capable of discriminating between chemicals in the solid, liquid and vapor states is described. The instrument is in the shape of a gun and uses a solid state detector and an NIR laser. It relies on gating techniques to minimize weight and lower energy needs.

L'invention concerne un instrument portable de spectroscopie Raman capable de différencier des substances chimiques dans les états solide, liquide et gazeux. L'instrument prend la forme d'un canon et utilise un détecteur à l'état solide et un laser NIR. Il repose sur des techniques de créneaux pour minimiser le poids et réduire les besoins énergétiques.
