Summary
Liquid chromatography and infrared spectroscopy are important techniques for the analysis of polymers and additives. By combining these techniques an on-line liquid chromatography — Fourier transform infrared spectroscopy system has been developed. Details of the interface consisting of a thermospray, moving belt and an optical reflectance accessory are presented. Applications include gel permeation chromatography of polymers and high-performance liquid chromatography of additives. The detection limits are in the 100-nanogram range.
