Excimer lamps emit high-energy 172 nm wavelength light by inducing a dielectric barrier discharge within a xenon gas. The eTOC is A smart user interface and the large touch-panel screen provide exceptional visibility and operability.
the rst TOC analyzer in the world to use a mercury-free excimer lamp. The indicator clearly shows the analyzer's status, such as standby, measurement in progress, or active warning.
The eTOC also features new “Active-Path” technology for transferring energy from the lamp to the sample. It ef ciently irradiates There is no need to squint at a small monochrome screen or go to a separately located monitor or controller to con rm data and

This new Shimadzu technology achieves both high measurement performance and high environmental performance.

The sample ow channel is integrated with the lamp.
The lamp surrounds the ow channel to irradiate samples with UV light more
ef ciently. Errors (red)
The simple shape of the ow channel minimizes contamination and carryover.
The lamp's outer material blocks UV light, which prevents accidental eye injuries
and unwanted ozone generation.

The small and lightweight eTOC can be installed on a tabletop or mounted to a wall or pole using an optional bracket kit.
In either case, a sampler can be attached to the side to calibrate the analyzer onsite.

That offers the exibility to choose the most convenient location for installation.

• UV light does not reach samples ef ciently, because it is absorbed by the air layer.
• Areas farther from the lamp are not irradiated suf ciently with light.
• UV light generates ozone inside the analyzer.
