Can the Barnstead NANOpure Diamond Analytial water system be considered as a reverse osmosis water system While it provides higher quality water is it correct to say it provides RO water
Answer
That's a great question.
You are talking about two different technologies that do similar things and that do different things.
Reverse osmosis is a membrane separation while the diamond is a chemical separation.
If you are talking about ability to remove ions (dissolved metals) then yes, a diamond or other deionizer would have a higher quality than Reverse Osmosis and could be used in its place as long as you don't want the water to be too pure and therefore ion aggressive as in an incubator or other device that has non-stainless steel metal that the water would come in contact with. Ion aggressive water will dissolve corrode metals except for high grade stainless steel.
Both technologies would remove Bacteria equally.
Both technologies would remove organic contamination but not at the same levels.
The Diamond would not remove pyrogens and the Reverse Osmosis will.
So in general, for chemistry testing protocols you can use the Diamond in place of Reverse Osmosis but in other application Reverse Osmosis has specific differences.
Nanopure Diamond systems actually perform best when pre-treated with reverse osmosis.
This high capacity four housing lab water system is designed to provide up to 3 l.p.m. of ultrapure water exceeding ASTM and CAP Type I, II or III specifications.
