Marco,

If you have used your divider, then have you considered the possibility that
you are producing H2 and O2 bubbles via electrolysis, and that the bubbles
are not air?  Certainly this happens at DC and low frequency AC.  Is there a
frequency above which polarity is switching too fast for H and O molecules
to have time to get ripped out of the water?

Have you considered using less complex solutions to dividers such as using a
long length of carbon impregnated black fuel or vacuum line hose such as one
can buy at an auto parts store?   They work fine as high value resistors
(and they don't produce bubbles!)
