Online TOC-Analysis

Shimadzu has released the TOC-4200 online analyzer. It covers features such as web-based monitoring and Modbus protocol for two-way digital communication, and it offers new functionality that provides a wider range of potential applications.

Increasing concern for the environment has grown the use of online TOC analyzers for environmental applications throughout the world, including emerging economies. There is a growing market for such analyzers and other instruments that can measure organic pollutants. For example, online TOC technology is applied to reduce organic pollutant levels in factory effluents in terms of Cod (chemical oxygen demand), and is increasingly being used to monitor water upstream from factory outflows.

Modbus two-way digital communication capability enables controlling two-way communication for multiple devices over a single integrated signal line, which also simplifies electrical wiring work. This allows connecting to twoway communication networks. The eco mode reduces waste by only using carrier gas and operating the sampling pump when it is needed for measurements.
