Description
The Shimadzu TOC-1000e total organic carbon analyzer is a compact on-line instrument from the eTOC series designed for automated monitoring of organic contaminants in pure and ultrapure water. In addition to total organic carbon (TOC), the system measures conductivity or specific resistance and water temperature. Its high sensitivity, with a detection limit of 0.1 µg/L, makes the analyzer suitable for water purification systems and water quality monitoring in the pharmaceutical, chemical, electronics, and other industries.
The TOC-1000e uses ultraviolet oxidation of organic compounds followed by conductivity detection. A mercury-free excimer lamp operating at a wavelength of 172 nm, combined with Active-Path technology, provides efficient UV irradiation of the sample and oxidation of organic contaminants without chemical oxidizing reagents. The instrument supports automated measurements at selectable intervals and remote monitoring of results via a network.
Features
- High-sensitivity TOC measurement with a detection limit of 0.1 µg/L and a standard measurement range of 0–500 µg/L, optionally extendable to 2000 µg/L.
- Simultaneous monitoring of total organic carbon, conductivity or specific resistance, and water temperature.
- UV oxidation using a mercury-free 172 nm excimer lamp and Active-Path technology.
- Automatic measurements with selectable cycles ranging from 2.5 minutes to 24 hours.
- Convenient operation via a 7-inch color touchscreen displaying measurement results and instrument status.
- Data transfer via USB and LAN, Modbus TCP/IP support, and remote result monitoring through a web browser.
- Optional automatic four-point calibration using a vial sampler for standard solutions.
- Support for 4–20 mA analog outputs and contact signals with an optional external I/O module.
- Compact design suitable for benchtop installation or wall and pole mounting using optional brackets.
Applications
- Pure and ultrapure water quality control in pharmaceutical manufacturing.
- Monitoring of water purification and treatment systems.
- Water quality control in the electronics and semiconductor industries.
- Water monitoring and testing in the chemical and food industries.
- Automated monitoring of organic contaminants in industrial water supply systems.
