Site selective real-time measurements of atmospheric N<sub>2</sub>O isotopomers by laser spectroscopy
We describe the first high precision real-time analysis of the N<sub>2</sub>O site-specific isotopic composition at ambient mixing ratios. Our technique is based on mid-infrared quantum cascade laser absorption spectroscopy (QCLAS) combined with an automated preconcentration unit. The QC...
