I'm trying to set-up a method for organic ICP-OES. The method uses oxygen gas (percentage can be varied in the ICP expert software). We currently have a mixed gas hooked up to the ICP-OES which consists of 20% oxygen and 80% argon.
My question is: Does the software think 100% oxygen is used in the method? So if I want to do a measurement with 20% oxygen will I need to set the method to 20% or do I fill in 100% because the gas is already mixed to 20%?
Thanks in advance!
