  Nitrous Oxide (N2O) emission reduction has gained large prominence recently due to its contribution to the climate change as a greenhouse gas. The United States Environment Protection Agency together with the United States Department of Transport has already regulated the N2O emissions from Light-Duty Vehicles and Heavy-Duty Engines. N2O measurement should be done from sample storage bags. Performance requirement of the analyzer is to be able to measure N2O gas concentration of sub-ppb order. N2O gas analyzer, QLN2O has been developed as one analyzer for integrated to MEXA-ONE. QLN2O is utilizing Quantum Cascade Laser and this analyzer can measure N2O concentration of ten ppb order.
