    I think you are correct about commercially available systems. However, I worked at a marine pollution studies lab for some time. We had an industrial-sized triple RO/DI system that absolutely did remove all particulate matter. The only ion left in the water was hydronium (H30+) but that is because water has an autoionization factor that makes it impossible to get achieve complete DI. Autoionization is the reason water can act as both an acid and a base--it ionizes itself. Water is truly amazing stuff!

    Absolutely. I meant for residential and consumer use systems that are promising absolute zero TDS, is hard to believe. My RO/DI system is pretty potent and I still get detectable TDS, but nothing that will create havoc. I get 4-5ppm TDS on an average day. Now, whem money is no object and you have a $30k purification system, I'm sure you can get <1ppm, like how you mentioned at your lab. It's amazing what big budget money can buy you. I just need to win the lottery now. :)
