How does NIR / FTIR modelling compare with NMR?
For NIR, one model per property, per stream is necessary. In many cases NMR needs only one model per property irrespective of number of streams. This greatly simplifies NMR modelling. Since NMR also includes a lot of process variation in its models, the models themselves are more robust and will not require the maintenance that NIR/FTIR needs. Model build time is also greatly reduced, meaning that NMR can get the analyzer on line and producing faster. As an indication, NMR can be on line in less than half the time it takes to implement an FTIR analyzer, even if using calibrations developed at other sites. The process NMR also requires less maintenance and has higher analyzer availability than many NIR devices.
