Hello all, Can anybody tell me, is de-ionized water also free from dissolved
gases? I ask this because I'm going to fill my HV water probe (see
http://www.iki.fi/dncmrc/work/hv_divider.htm) with distilled and de-ionized
water instead than distilled and boiled water. This thing is going to be
2.7 m tall, containing 20 liters of water inside. We are going to hang it
from the roof (16 m high) on the top of the Thor TC. Regards.

Question: Is de-ionized water also free from
dissolved gases?
No.. It is not. you need to heat it to evolve the gases (distilled water tends
to have fewer dissolved gas, because of the production process).
Simply pouring the water from one container to another will cause it pick up
some gas, too... Unless you're pouring in a blanketing atmosphere of something
with low solubility (or water vapor).

Try looking at his link. Also once you put high voltage to it, could it be
there will be gas formed?

NO.....NO ! Deionized water has gas and soluble salts contained in it.
It has " hard water" elements like calcium removed , but it is not as pure as
distilled. It makes a good input for a still to make distillation of
better quality. Robert H.
