This proprietary advanced oxidation process, referred to as the VANOX POU system, will consistently reduce TOC to 0.5 parts per billion (ppb) and can treat seasonal TOC variations in feed water. This is important, since TOC elevations above 1.0 ppb can directly affect the manufacturing process, significantly impacting product yields.
Advanced oxidation produces hydroxyl radicals that attack and break down difficult organic compounds measured as TOC. Although advanced oxidation has been used in industrial applications for years, it had not been refined enough to minimize key contaminants and thus improve various tool applications. The Siemens VANOX POU system has made improvements in the reactor design, allowing reductions in power and capital costs and reductions in chemical use.“The Siemens VANOX POU system creates a more effective radical for TOC reduction compared to common AOP processes,” said Bruce Coulter, Ultrapure Water Technical Manager for the Microelectronics Group at Siemens Water Technologies, “and it effectively removes troublesome organics such as urea, 2-propanol (IPA) and Trihalomethanes (THMs) found in semiconductor waters.”
The VANOX POU system will also deliver critical control temperature, low trace metal contaminates and reduce particles to less than 100 units per liter at .05 microns. The current industry standard for POU particle reduction is 200 to 500 units per liter.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
