Argon analysis

How to measure the argon content in the ammonia synthesis off-gas using phase measurement? Could someone with more experience give me some advice?
What instruments are available? Call:
I also want to know how to measure the purity of argon. I looked at the **standards**, but I didn’t quite understand it; it seems quite difficult. Is there a simpler way?
I’d like to know that too, because the amount of argon used in our company is estimated – does anyone have any advice?
I want to know that too. The amount of argon used in our factory is also estimated, and this often leads to abnormal reactions in the synthesis towers. How do you calculate it?
I determine the content in the fresh gas based on the Ar/N2 ratio in the fresh gas, which corresponds to the ratio in air; I then measure the methane content in the fresh gas. By using the Ar/CH4 ratio in the fresh gas, I estimate the contents in the system through material balance calculations. The composition of the released gas can be calculated based on solubility. The CH4 content can also be measured, approximately estimated based on the Ar/CH4 ratio in the fresh gas. Refer to the article \"Material Balance of High-Pressure Circuits in Ammonia Synthesis\"
Our factory uses pressure swing adsorption technology for the recovery of synthetic purge gas, but the adsorbent is unable to absorb argon present in the purge gas, resulting in argon circulating within the system. Could anyone advise me on any methods or instruments available for analyzing argon?
