I am a TDI Advanced gas blender (# 201940) I am having some trouble getting UHP (Grade 5) Helium from my local suppliers. A question my rep asked was could I use Medical grade Helium, I didnÃÕ have an answer for him and I have been unable to find any documentation on this to give to him. So I am looking for some clarification on weather or not we can use Medical grade helium for Tri Mix blending or if it must be UHP Grade 5.
Thanks
