Recently we developed an original method using laser spectroscopy for determining, in closed containers, pressure and content of a particular gas, in our case CO2.
The invention has been patented jointly by National Research Council (CNR) and University of Padua.
The technology at the base of the product is related to the applications of the recently developed diode lasers to gas spectroscopy.
Laser spectroscopy is, since quite time, an accepted and proved method for trace gas detection; laser spectroscopy relies on the spectral proprieties like very narrow bandwidth of lasers that can be made tunable in order to scan the molecular absorption lines of many molecules of interest (like O2, CO2, CO, and many others). In this field we carried our other projects such as the development of a spectroscopic laser apparatus and method for non-destructive monitoring of oxygen in sealed containers for pharmaceutical applications.
We are detecting the gases described above but it's possible to measure also Carbon Monoxide CO,Nitric Oxide NO,Nitrogen Dioxide NO2,Nitrous Oxide N2O,Methane CH4,Acetylene C2H2,Hydrogen Fluoride,Hydrogen Chloride HCI,Hydrogen Bromide HBr,Hydrogen Iodide HI,Hydrogen Cyanide HCN,Hydrogen Sulfide H2S, Ammonia NH3,Formaldehyde H2CO Phosphine PH3.
