A Delta V Plus isotope ratio mass spectrometer (IRMS) interfaced with a modified Gas Bench (for N2O isotopic analyses) and an Elemental Analyzer (for CNS isotopic analyses of solid samples).
A Class 1000 Clean Lab designed for the processing of low-nitrogen samples. Due to human emissions, air contains a significant amount of nitrogen pollutants including particle-associated nitrogen, NOx, and ammonia. This lab is equipped with a HEPA and AMC filtration system to remove these airborne nitrogen pollution.
A room dedicated to the bacterial conversion of nitrate to N2O for isotopic analyses.
