High-accuracy Measurement of TOC below 5 PBB Levels


The current regulatory demands of the industry require analytical instruments that can measure at increasingly lower detection limits with high precision and accuracy. For example, some ultrapure applications in TOC require trace level detection to ensure highly accurate and precise results. The Shimadzu Wet Chemical TOC-VW is the only TOC analyzer on the market that offers three oxidation techniques — UV light, persulfate, and heat — in a single instrument. This allows for optimal TOC sensitivity with a method detection limit of 0.5 ppb. This application note demonstrates how the TOC-VW meets the demands of ultrapure applications by achieving practical quantitation below 5 ppb.
