  • Page 55: Special Considerations For H 2 O Measurement

    HALO Users Manual Revision G 8 Special Considerations for H O Measurement Cavity ring-down spectroscopy (CRDS) is a powerful technique, but it is not without limitations. This section addresses those limitations and is intended to help you make more accurate measurements. The first requirement for successful CRDS measurements is that there is no overlap between the spectra of the species being measured and that of the carrier gas and its other components.
  • Page 56 HALO Users Manual Revision G Hydrogen (H Hydrogen is a homo-nuclear diatomic molecule that has no measurable absorption in the NIR. The water absorption peaks are slightly narrowed in Hydrogen. This provides increased sensitivity of H O measurements (vs. N ), but with a slightly reduced upper limit reading.
