Features and Benefits
• Measurements of site-specific isotopic nitrogen in N2O (14N15N16O, 14N15N16O, N2O)
• Measurements of δ15N, δ15Na and δ15Nb enable quantification of N2O sources and sinks
• Measurements of δ17O and δ18O allow quantification of nitrification processes.
• No cryogens or water cooling
• High-resolution absorption spectra are viewable for instrument diagnostics
• (optional) Multiport Inlet Unit enables measurements at multiple locations
• (optional) Dynamic Dilution System extends upper range of measurements by 100x
• (optional) Manual Injection allows measurements of small volume samples via syringe
