Sensitivity improvement, photometric accuracy, and instrument stability are evaluated by comparing dual-beam spectra with conventional single-beam spectra. Dual-beam FT-IR data acquisitions require an order of magnitude less measurement time than single-beam acquisitions for spectra of comparable signal-to-noise ratios. Application of dual-beam FT-IR for analysis of a highly transmitting sample is discussed. Single fiber analysis without masking and without an infrared microscope is described.", pages = "628-632", url = "http://www.ingentaconnect.com/content/sas/sas/1986/00000040/00000005/art00008", doi = "doi:10.1366/0003702864508520", keyword = "FT-IR, Dual-beam FT-IR, Dual-beam interferometry" }
