Organic compounds present in ultrapure water (UPW) can pose serious problems for production processes within the electronics industry. UPW ITRS (International Technology Roadmap for Semiconductors) targets for advanced semiconductor applications are stringent, with TOC limits of 1 ppb for critical organics and 3 ppb for non-critical (volatile) organics. Organics speciation of the UPW system allows for detection of the critical organics and troubleshooting while serving as a method to support change control.  Read more
