High Precision Trace Gas Measurements with Quantum Cascade Laser Spectroscopic Instruments

Not Accessible

Your library or personal account may give you access


Newly developed quantum cascade laser spectroscopic instrumentation allows high precision measurements of atmospheric trace gases, including measurements of small fractional (<10−3) changes in stable gases (e.g. N2O), and isotopic ratios (e.g. 13CO2/12CO2, 13CH4/12CH4).
