Fourier Transform Infrared Spectroscopy Fourier transform infrared spectroscopy (FTIR) coupled with an in situ probe is a powerful technique for instantaneously monitoring chanical species including monomers in a water-soluble polymerization matrix. Monomer concentrations can be determined from a partial least square (PLS) calibration curve estabhshed from a sales of reference samples with known monomer concentration generated by HPLC analysis. The determination of residual monomer is limited only by the sensitivity of the detector. Calihration curves are product and formula specific. [Pg.391]
