Real-time measurement of CO 2 isotopologue ratios in exhaled breath by a hollow waveguide based mid-infrared gas sensor

Zhou, Tao Wu, Tao Wu, Qiang

A hollow waveguide (HWG) based mid-infrared gas sensor using a 2.73 µm distributed feedback (DFB) laser was developed for simultaneously measuring the concentration changes of the three isotopologues 13 CO 2 , 12 CO 2 , and 18 OC 16 O in exhaled breath by direct absorption spectroscopy, and then determining the 13 CO 2 / 12 CO 2 isotope ratio...

Methane detection with a near-infrared heterodyne phase-sensitive dispersion spectrometer at a stronger frequency modulation using direct injection-current dithering

Zhang, Haojie Wu, Tao Wu, Qiang

Heterodyne phase-sensitive dispersion spectrometer (HPSDS) retrieves the concentration of gas samples by measuring the refractive index fluctuations near the molecular resonance. Compared to previous HPSDS studies focusing on pure intensity modulation, it is attractive to investigate the performance of HPSDS sensor based on a distributed...
