Hi,
What kind of test are you looking for?
Have you considered the cost of changing the refrigerant? It might be more expensive.
Cheers

hı LANA,
I am thinking only to change refrigerant brand,for example instead of dupond to use akmera,but I want to make quality control for new refrigerant,If you have experiences about test method how to do it,please share with me.
OH I got you. I reckon you have the same problem as we have here : Refrigerants with well known brands but the gas inside is something else.
We had a party of R134a cylinders imported here and guess what, they were flammable :eek: .
If your problem is the same as I mentioned, then try to find the actual representative who would give you the real stuff.
Good luck

Gas Chromotagraphy or Mass Spectrometery
Either way its not cheap or simple.
Most distributors offer a GS service of some kind. The Chem Eng dept at Tehran University used to have a good but rarely used GC set up but not sure of the status now as that was 8 years ago.
If its acid and moisture testing only then look at the Checkmate unit from Refrigeration Technologies.
Download a copy of ARI 700 from the ARI website which has the test procedures for common refrigerants.
