Kaiser has announced the release of the RamanRXN 1000 Raman analyser which provides the fluorescence rejection of a FT-Raman spectrometer but with the ease of fibre-optic interfacing of a dispersive Raman analyser. While 785nm excitation remains the most universal wavelength range for petrochemical and pharmaceutical Raman applications, some applications such as early stage “dirty” crystallisation, biofuels, polyurethanes, heavy hydrocarbons and some colourants/pigments exhibit fluorescence too intense to allow the application to be addressed with 785 nm excitations. The RamanRXN 1000 provides an effective route for in situ monitoring of these applications, filling a niche where fluorescence cannot be overcome using 785 nm excitation. Raman measurements can be made on-line allowing users the potential to develop process control methodologies rather than end-product testing. The analyser is offered with either iC Raman 4.1 for reaction development and understanding or synTQ-Lite for process monitoring and control where compliance to 21 CFR Part 11 and interface to data historians are required.
