Aerodyne’s family of laser trace gas monitors provide real-time molecular monitoring with fast time resolution (as fast as 10 Hz) and with exquisite sensitivity – in the low parts per trillion range for many species. These instruments rely on our Astigmatic Multipass Absorption Cells (AMACs) to provide enhanced sensitivity.
The Mini Laser Trace Gas Monitor is a compact, single laser trace gas monitor. It is our smallest and most economical laser trace gas instrument. The instrument can be configured to detect many trace gas species including NO, N2O, NO2, NH3, CO, CO2, CO2 for delta13C, delta18O and delta 17O, CO2 for delta17- CO2, CH4 for delta13CH4 and deltaCH3D, C2H6, COS, HCHO, O3 and many others. In some cases, multiple species can be detected simultaneously. For example: N2O, CH4 and water; N2O, CO and water; N2O, CO2 and water; CO, CO2, N2O, and water.
The Dual Laser Trace Gas Monitor allows for the simultaneous measurement of multiple species using two multiplexed laser trace gas monitors. The list of molecules includes NO, N2O, NO2, NH3, HONO, HNO3, CO, CH4, C2H4, HCHO, CHOOH, SO2, COS, O3, HOOH and others. Choose between two versions - one with enhanced sensitivity , the other with enhanced time response.
The Carbon Dioxide Isotope Monitor provides real-time measurement of the isotopic ratio of 13CO2 and CO18O in ambient air samples. Its precision is unrivalled among optical isotope monitors and approaches that of Isotope Ratio Mass Spectrometry – but with real time results even in a field setting. We also offer a version of the CO2 isotope monitor that simultaneously measures the isotopic composition of water vapor and a version for the "clumped" isotopes of CO2.
Isotopic Monitors for CH4 and N2O are now available. These instruments are specialized versions of the Dual Laser instrument described above. For methane, we measure the isotopic ratios of 13CH4 and CH3D. For, nitrous oxide, we report the isotopic ratios of 15N14NO, 14N15NO and NN18O.
