I'm running some experiments in which I need to get a precise concentration value for ethanol gas.
I'm purging synthetic air (500 ml/min) in a gas bubbler filled with 100% liquid ethanol at a constant temperature of 25 °C, then the output should be a 100% ethanol vapor.
I would like to know how to get different concentrations of ethanol gas without mixing it with other synthetic air. Would some dilution of the ethanol solution work?
Any suggestion is really appreciated.
Thank you all.
Hi Zelio, I've not worked with ethanol in this way, but with water it's not easy to achieve saturation and very good, active T control is required, Paul.
Dear Paul Milham,
thanks a lot for your reply. I'll try to modify my setup in order to get a dilution after the bubbler. I think it's the easiest way.
Thanks again,
Zelio
