Water vapor δ2H and δ18O measurements using off-axis integrated cavity output spectroscopy
Water vapor δ2H δ18O measurements cavity output spectroscopy
2010/2/8
We present a detailed assessment of a commercially available water vapor isotope analyzer (WVIA, Los Gatos Research, Inc.) for simultaneous in-situ measurements of δ2H and δ18O in water vapor. This me...
Broadband Cavity Enhanced Differential Optical Absorption Spectroscopy (CE-DOAS) – applicability and corrections
Broadband Cavity Absorption Spectroscopy applicability corrections
2010/2/8
Atmospheric trace gas measurements by cavity assisted long-path absorption spectroscopy are an emerging technology. An interesting approach is the combination of CEAS with broadband light sources, the...
A cavity ring down/cavity enhanced absorption device for measurement of ambient NO3 and N2O5
cavity ring down cavity enhanced absorption device ambient NO3 N2O5
2010/2/8
An inexpensive, compact instrument for the sensitive measurement of NO3 and N2O5 in ambient air at high time resolution is described. Light from a red-emitting laser diode (≈662 nm) is coupled off-axi...
