DAL MORO RICCARDO - Raman spectroscopy for inline analysis of combustion processes
Research project
The objective of the research project is the development of a Raman Spectroscopy set up for the inline analysis of combustion process (eg, rocket combustion, jet engine combustion, ecc ecc). Raman spectroscopy is an analytical technique where scattered light is used to analyze a sample. This technique is widely used for solid and liquid samples analysis. The problem with Raman spectroscopy for gas analysis is the low density of the samples. In addition, combustions are very fast processes and we need to minimize the acquisition time. Requirements for the measurement set up are: - Fast response - High sensitivity - Ability to perform analysis in harsh environments - Multispecies gas detection In order to achieve appreciable measures an improvement of the basic set up is needed. It is possible to act in 4 different ways: - Laser source improvement - Implementation of a multipass laser beam path - Spectrometer improvement - Detector improvement A trade off will be made between these aspects, because each of them affects the complexity, efficiency and reliability of the system. The first step will be the implementation of a multipass beam path.
