Duisburg/Germany — Shimadzu has released the TOC-1000e, the first analyzer in the eTOC series of on-line TOC analyzers designed for pure water applications. The eTOC series’ main focus is on miniaturization, high sensitivity and a mercury-free oxidation technique. According to the manufacturer, the TOC-1000e system has the world’s smallest and lightest cabinet and provides high-sensitivity detection, making it ideal for fields requiring high-purity water applications. This covers manufacturing, including pharmaceuticals, semiconductors, food & beverages, chemistry and precision equipment.

Total organic carbon (TOC) analyzers are used to rapidly quantify organic substances in water, allowing decisive process intervention. Among many fields of application, they are used mainly for water quality control and environmental investigations. Shimadzu’s TOC analyzers are well-suited to laboratory and on-line analysis of environmental and waste water. The eTOC series will be the company’s first on-line TOC analyzer designed especially for pure water measurements.

The “Active-Path” flow line design integrates sample flow channel and the light source and minimizes sample residue in the flow channel, so that high sensitivity is maintained.

Conventional TOC analyzers for pure water utilize mercury UV lamps as the light source within the instrument. To provide a more environmental-friendly alternative, the eTOC series is the first analyzer in the world to use an excimer (short for excited dimer) lamp rather than a mercury lamp. The “Active-Path” flow line design maximizes lamp power by integrating the sample flow channel and the light source. This minimizes sample residue in the flow channel and eliminates interfering air layers, so high sensitivity is maintained over long-term use. This new design also contributes to making the eTOC series instruments small and light.
