In this project the advantages given by the simultaneous use of infrared spectroscopy (FTIR) and mass spectrometry (MS) in-situ analysis of environmental pollutants and on-line analysis of industrial processes is studied in this project.
The main goal of the project is the development of new mathematical methods for deconvolution of identity and quantity of individual compounds present in environmental/industrial samples on the basis of simultaneously measured mixture spectra of both the techniques. When the analysis errors of the MS and FTIR methods do not correlate their combination will give more accurate solution for the concentration of the compounds as can be seen in figure 5.
The research group consists of VTT Chemical Technology and Laboratory of Computational Engineering and industrial partners. The funding for the project is provided by the Technology Development Centre (TEKES) of Finland. The project will continue to the end of year 2000.
