On-Line TOC Analyzer

On-Line TOC Analyzer

World’s-First Ultra Slim TOC Analyzer using Mercury-free Excimer Lamp.
New Advanced Active Path Technology.


Shimadzu eTOC has very high sensitivity and low detection limits, reaching 0.1 µg/L, making it perfectly suitable for ultra-pure water measurement.

The eTOC is the first TOC analyzer in the world to use a mercury-free excimer lamp. Excimer lamps emit high-energy 172 nm wavelength light by inducing a dielectric barrier discharge within a xenon gas.

The eTOC also features new “Active-Path” technology for transferring energy from the lamp to the sample. It efficiently irradiates the sample inside the lamp with ultraviolet light to reliably oxidize organic matter.
