The analytes were detected and identified with Fourier transform infrared spectrometry. A commercial mobile-phase elimination interface (LC-Transform ) was employed. A fixed-integral restrictor afforded the decompression zone between the column and germanium disk where the analytes were deposited. Excellent-quality infrared spectra were obtained for all eight separated analytes.", pages = "1791-1795", url = "http://www.ingentaconnect.com/content/sas/sas/1997/00000051/00000012/art00004", doi = "doi:10.1366/0003702971939848", keyword = "SUPERCRITICAL FLUID CHROMATOGRAPHY FOURIER TRANSFO" }
