According to the manufacturer, this spectrometer is intended for chemical industry laboratories that perform a large number of daily measurements for QA/QC analysis or at-line process support. It is particularly adapted for applications in the fields of polyols and polyurethanes. The MB3600-CH70 is a maintenance-free bench analyser enabling fast determination of several quality properties in liquid chemicals, in particular hydroxyl value (OH). The FT-NIR spectrometer features a set of pre-loaded calibration models with operator interface for immediate OH value determination in different groups of polyols and derivatives. Users can access an extensive library of FT-NIR spectra and additional custom calibrations can be developed on the MB3600-CH70 for rapid measurement of more quality parameters such as iodine value, acid value, saponification number, amine content, isocyanate content, and TDI isomer ratio.
