Re: [MW:31349] How to check Argon Gas Purity?

Dear All

Checking Impurities in Argon gas cylinder is still a secret with the Gas manufacturers.

We need to check following impurities in Ultra high pure Argon gas # CO2, CO, oxide of nitrogen, hydrogen, nitrogen, hydrocarbons, sulphur compounds, mercury, chlorine.

But all Argon gas manufacturers in India are able to check only dew point, moisture and oxygen .

Can anyone help please ..

Shaw meter will only measure the dew point..

How to measure other impurities like moisture, oxygen, hydrogen, oxides of nitrogen, chlorine, sulphur, etc ?

Shaw meter available.

But always better weld in a piece and then proceed to job. Due to improper cleaning base metal also will result this black mark

Dear All,

we are doing Aluminium alloy welding by (TIG) process, during welding we observed black mark around the welding for some argon gas cylinders.

Please suggest how to check the gas purity level and any instruments / gauge are available.

Thanks & Regards,

Trivikram
