Copper lines for copper analysis

DearI'm just moving to a new building with our new ICP-MS iCAP RQ and will amongst others be analyzing for Cr, Co and Cu. To carry the Argon gas from the basement to our lab at the 2nd floor copper lines for medical gasses have been installed.Will that work? Or will I get contamination form the lines? How can I check that I don't?Best regardsPer Bo jensen
