We use reverse osmosis for obtaining deionized water. Recently the conductivity of this water has increased to 15 uS/cm. Meanwhile the tap water has the conductivity of 1500 uS/cm.
Thanks a lot for your kind response. We dont use this water for HPLC. we just use it for routine applications in water and soil analysis. and we always use blank. from the analytical point of view is this water fine?
We are now using reverse osmosis water, which we decided to use instead of distilled water, due to its problems. Is it ok that we use RO water instead of distilled water?
