APACT16 report

APACT16 Session report by John Andrews, MSG committee member

The MSG sponsored a lively session at APACT16 in Chester on “Advances in Process Raman Spectroscopy” There were three interesting talks in the session. Dr Paul Dallin of Clairet Scientific spoke on “25 Years of Process Raman, What have we learnt and where are we going?” which was both an interesting and an amusing history of how the technology and applications have developed over the years.

Mari Tenhunen (Timegate Instruments, Finland) presented on “Pulsed laser excitation and fast electrical detection for Raman scattering – time gated Raman in process monitoring applications – Case Studies from the mining industry” Time gated Raman is an exciting new development which enables the Raman and fluorescence signals to be separated. In process Raman many samples can fluoresce, often due to impurities, and the ability to obtain Raman spectra from such samples promises to open up some new opportunities for the technique.

Julian Meyer-Kirschner (pictured below) of Aachen University spoke about “Quantification of the influence of particles on Raman spectra based on Indirect Hard Modelling” This talk looked at the Raman spectra obtained from microgel synthesis and discussed a novel method for separation of the main component concentrations from the effect of particle scattering.
