Ammonia (NH3) decomposition facilitates hydrogen production.
Monitoring the
reactants and contaminants of ammonia decomposition, including NH3, H2, N2, and
H2O, is highly important for catalytic performance as well as activity measurements.
In this work, an Agilent 990 Micro GC system configured with an Agilent CP‑Molsieve
channel and an Agilent CP-Volamine channel is demonstrated to analyze NH3, H2, N2,
and H2O across a wide concentration range.
Notably, the analysis can be completed
within one minute.
The method's performance, including repeatability, linearity, limit
of detection (LOD) and carryover was evaluated, and the results were satisfactory.
