Notes:
Xenon is investigated as a mobile phase for on-line capillary supercritical fluid chromatography-Fourier transform infrared spectrometry (SFC-FTIR). Polycyclic aromatic hydrocarbons, aromatic isocyanates, and epoxy acrylate oligomers are analyzed as examples to show that xenon has similar selectivities and solvating powe to CO2. Its optical transparency makes it ideal for IR detection. A stop flow system is constructed to increase the sensitivity of spectra measured from compounds which are weak IR absorbers.
