Gas chromatography spectrometry NH3, N2O, NO, NO2

What pillars used to use?I am doing SCR denitration, I need to measure N2O, I want to consult with the landlord.

Do you have any good way?If I choose a molecular sieve 5A PLOT column to detect NO2, NO, N2O, and NH3?Mainly want to detect NH3 and N2O, what should I do?

You can detect the two columns, but you can use two columns, but you have to modify the airway, that is, add the gas control valve on the panel

If the detected gas is collected by the gas collecting bag, what should be added to the six-way valve?

First, you have to look at what column is detected by your gas chromatography, NH3 and NO2 should be difficult to measure the estimate at the same time.After collecting the gas bag, the six-way valve can be acceded by extrusion.
