| Popis: | Nowadays optical methods in the field of gas analysis are actively developing. A new non-invasive method of gas analysis using Raman spectroscopy is discribed. Using a high-resolution double concave grids operating in the fourth diffraction order makes it possible to implement a sufficiently high spectral resolution to detect molecules at concentrations up to ppb units. This allows to use this method for the analysis of exhaled air as well as for a wide range of environmental monitoring tasks |
