The Cascada AN-water System is fed with partially purified water. The unit produces extremely high ultrapure water for critical laboratory applications suitable for all analytical and pharmaceutical applications.

Total organic carbon (TOC) provides a good indication of the overall levels of organic contaminants in purified water.

A Cascada™ AN-water System was fed with water from reverse osmosis (RO) permeate water with a conductivity of 28 µS/cm and a TOC of 60 ppb C. The unit was operated intermittently and product water dispensed to simulate typical use patterns. TOC was logged online using an Anatel A100 analyzer.
