This is correct as 0 ppm is not easily achieved.

That would require distillation, correct?
Such a thing as absolutely 100% water without a single molecule of something else, doesn’t exist on this world.

That makes sense. But, in regards to RO water, distilled is generally lower, if I’m not mistaken.

I’ve read this but going to my RO place for water their water had 274ppm worth of stuff in it, which seemed high to me. That being said my distilled water says absolutely nothing in regards to ppm

Theres deionizers that use carbon filters to get just about everything out
RO alone won’t.
Distillation will but that takes alot of energy especially for water
Theres a reason they use RO for desalination instead of evaporation

Or RO at the grow will read minimal when the filter is new. I have always been under the impression that distilled water was “0ppm”. But, there’s far more precise measurements than that.

Yes I as well, as distilled is what is put in the rad on vehicles, specifically because the mineral/salt content is “non-existent”, so as not to corrode anything

It probably is “0 ppm”. But in more sensitive contexts they look in ppb, ppt, even lower than that.

Absolutely pure water actually has tremendous solvent power, dissolving metal, glass, and just about anything else. It is called the “universal solvent” for a reason. For that reason even in sophisticated lab environments it can’t be prepared absolutely. The presence of even a tiny amount of solute tames this tendency enough for it to be the safe chemical we know and love. This article describes a sensitive neutrino detector that used very pure water. The slightest skin contact with it can harm people, leaching anything remotely soluble right out of your skin. And even that water is not truly pure.

That article claims neutrinos can travel faster than light.
But otherwise, is super interesting

I was meaning just that with saying there’s far more precise measurements than that. Ppm is pretty large on the scale of things

You’re right, 100% pure water isn’t a tangible reality on earth.
When I was in pharma, our water purification was as follows—water softener, reverse osmosis, de-ionization, and the three stages of distillation. It was so pure, it was used to create injectible formulations (it was labeled throughout the build as water-for-injection).
Even that water isn’t 100% pure.

I thought sterile water for injection was about reducing TOC, not salt/solid removal. For instance, milliQ water is pretty much just RO water that’s been UV irradiated up the wazoo
Our RO system we use for irrigation was actually part of a Pfizer sterile drug line that we bought cheap at an auction lol. We uninstalled like 3/4 of the system because it was total overkill

So screenshot it?
There is a keyboard key called print screen which will take a screen shot of the page. usually the key is marked “PrtSc”
If those options dont work just take a picture with your phone.

You’ll have to know the retention time as the peaks aren’t labeled
So share the retention times? 
Were not asking for a perfect coa just a simple before and after result. Most people on this thread can read or understand a basic chronograph.
You know that a COA or a graph speaks for a lot more than any words or pictures ever could.

It is indeed, but the first three steps are taken to improve the longevity of the three-effect distillation unit.
