Pharmaceutical manufacturing depend on several strict qualitative and quantitative control measurements including the concentration/purity, color, etc. Oftentimes, this requires monitoring a reaction in real-time. tec5’s low maintenance spectrometer systems provide fast, reliable spectral data. The systems can easily be incorporated into in-line production to monitor reaction processes. This cuts out the requirement to stop a reaction and remove a sample for analysis in a separate area. Spectrometer systems can be encased in IP54 to IP69 allowing the systems to be incorporated near the reaction vessels to avoid long fiber-optic cables.
