Denzel, G. Hancock, M. Islam, C.E. Langley, R. Peverall, G.A.D. Ritchie, D. Taylor Title: Trace species detection in the near infrared using Fourier transform broadband cavity enhanced absorption spectroscopy: initial studies on potential breath analytes Journal/Source: Analyst,136, 801-806, (2011); DOI: 10.1039/C0AN00462F Data: table Energy/Wavelength range: 1671.9 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The absorption cross-sections for acetone and isoprene have been measured with an instrumental resolution of 4 cm-1 and are found to be 1.3 ± 0.1 x 10-21 cm2 at a wavelength of 1671.9 nm and 3.6 ± 0.2 x 10-21 cm2 at 1624.7 nm, respectively.
