| Zusammenfassung |
| We are currently developing a middle-infrared laser-based sensor platform that
is capable of monitoring a wide range of species with high sensitivity, accuracy
and selectivity. The laser technology covers the O-H, N-H, and C-H stretch region
between 3-4 microns and the C-O and N-O stretch region between 4-4.6 microns
and is being used to monitor key greenhouse and other trace gases such as CH4,
CO2, CO and N2O. We will present results from laboratory tests of sensitivity,
stability, and accuracy showing ppb level performance for carbon monoxide and
methane. For CO, this level of precision is key for source attribution in background
monitoring applications and for CH4 it is required for greenhouse gas monitoring. |
