New procedure for selection and validation of “reference” TOC analyzers for ultrapure water based on experimental performance

Nathalie Guigues, Pierre Caruso, Merina Corpinot, Stéphane Bruder et autres

In ultrapure water production, maintaining low Total Organic Carbon (TOC) levels (below 5 µg/L of carbon (µg/L-C)) is essential. For high TOC levels, calibration typically involves standard solutions. However, for low TOC levels, standards cannot be used due to susceptibility of aqueous …
