[Dsg-rtpc] RTPC drift gas bottles

[Sebastian Kuhn]

Dear all,

thanks for changing out the empty RTPC HeCO2 gas bottle. I wanted to ask whether someone might still have the tag it came with, where it says what the certified ratio He/CO2 is? We noticed that the present bottle has been certified at 20.7% He (+/- 2%) and the next one in line is 21%. This might be useful to know for us later.

Thanks - Sebastian
