How to measure the water content in ionic liquid

The water content measurement meter ~~~ The hydrophilic ionic liquid is easy to absorb. We generally heated to about 150 degrees before the vacuum is dry 12h before it is used

V \u003d m/3
v1 \u003d m1/ρ1
v2 \u003d m2/ρ2
v1+v2
m1+m2

Only the moisture tester, and it is very accurate.

If only ionic liquid and water, the content of water can be calculated with density method.
