Features and Benefits

• Measurements of site-specific isotopic nitrogen in N₂O (¹⁴N¹⁵N¹⁶O, ¹⁴N¹⁵N¹⁶O, N₂O)

• Measurements of δ¹⁵N, δ¹⁵N^a and δ¹⁵N^b 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
