Out of boredom, and because there were a handful of floating balloons at work that were not needed anymore, I decided to see what was inside of them. Brought in my Divesoft analyzer. Put a piece of gorilla tape on the balloon to prevent rapid exhausting of the contents. Got everything ready and put an Xacto through the tape. Did exactly what I was trying to do. Controlled venting. Shoved the sample hose into the slot and waited a few moments for the numbers to stabilize. Hint, It's not 100% He.
6.2% O2
82.2% He
There has to be some O2 blended into that. Not heliair, that would only come in at 3.7% O2 given the fraction of He.
I have no way of telling what the mystery 11.6% of that mix is.
Something to think of the next time someone shows up with some "balloon grade" helium and wants to go diving with it.
This was one of the more floaty balloons. I'll try and get one of the not so floaty ones to see what is in that.
