Fourier transform infrared spectroscop sample preparation

Spectroscopic techniques are powerful process analytical tools. They are unparalleled in terms of molecular specificity, minimal sample preparation that translates to speed, and are capable of inferring physical properties [63,67,68]. Mid-infrared Fourier transform spectroscopy (FTIR), near-IR (NIR), and Raman spectroscopic techniques are the workhorse tools commonly used to monitor online polymerization processes.
