Polymer analysis by column liquid chromatography coupled semi-on-line with Fourier transform infrared spectrometry

Additives in polypropylene and PVC were identified by solvent-elimination based coupling of reversed phase column LC and FTIR spectrometry. A spray-jet interface was used to deposit the effluent from a narrow bore LC column on a zinc selenide window. Deposited additives wre analysed by FTIR transmis...

Description
Summary:Additives in polypropylene and PVC were identified by solvent-elimination based coupling of reversed phase column LC and FTIR spectrometry. A spray-jet interface was used to deposit the effluent from a narrow bore LC column on a zinc selenide window. Deposited additives wre analysed by FTIR transmission microscopy, with detection limits in the low-nanogram range. (Abstract quotes from original text)
