HI Marilyn--

I tried to conserve O2 and cap the line when it was not running (no, I don't put it in standby mode).  But then you have to remember to uncap it...

So I don't use the cap, and it takes a long time to bleed out a tank.

take care,

gerry

Dear Isogeochemists,

A question: do you run your Costech EA with a cap on the VO2 vent or without a cap? Directions are “skimpy” with respect to this connection.

Curious, Marilyn
