TOC-1000e: On-line TOC Analyser Designed for Pure Water Applications

Apr 23 2021

Shimadzu's TOC-1000e is the first analyser in the eTOC series of on-line TOC analysers designed for pure water applications. The eTOC series’ main focus is on miniaturisation, high sensitivity and a mercury-free oxidation technique. The pioneering 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) analysers 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 world-leading TOC analysers are well-suited to laboratory and on-line analysis of environmental and waste water. The eTOC series will be Shimadzu’s first on-line TOC analyser designed especially for pure water measurements.

Minimum footprint, highly sensitive, environmental-friendly

The TOC-1000e provides enhanced robustness in the ultra-low measurement range. With its small footprint of less than A4 size, it can be installed flexibly – either as table-top, wall-mounted or pole-mounted.

Conventional TOC analysers for pure water utilise mercury UV lamps as the light source within the instrument. To provide a more environmental-friendly alternative, the eTOC series is the first analyser in the world to use an excimer (short for ‘excited dimer’) lamp rather than a mercury lamp.

The ‘Active-Path’ flow line design maximises lamp power by integrating the sample flow channel and the light source. This minimises 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.


The TOC-1000e combines high-sensitivity and easy-to-use features benefiting effortless data management, efficiency and handling. To mention just a few:

  • State-of-the-art oxidation technology in the smallest casing
  1. The TOC-1000e provides high sensitivity with a detection limit of 0.1 μg/L. It is housed in the world’s smallest and lightest cabinet and equipped with the industry’s largest colour touch panel, providing exceptional visibility, simplifying operation and allowing effortless management of compliance relevant data. In addition, the novel fluid system minimises sample residue in the flow channel, ensuring that high sensitivity is maintained.
  • Easy-to-use and to maintain design improves efficiency
  1. The eTOC series has a simple design, and parts typically do not need to be replaced for one year; this increases efficiency by reducing maintenance and re-validation effort. Consumable parts (excimer lamp and pump head) can be removed and installed without tools. Using an optional sampler, the analyser can be calibrated or validated (confirmation of manufacturing process validity) at the operating site. Certified standard solutions particularly for this series are available; they save customers the time and expense of purchasing and preparing items from a reagent manufacturer, and reduce mistakes caused by human error. In addition to analog interface and digital I/O, measurement data can be output to a printer or USB flash drive, or browsed and acquired via a built-in web server.
  • Support for Regulatory Compliance
  1. eTOC’s highly sensitive UV oxidation-conductivity method for ultra-pure water monitoring is compliant with regulatory requirements such as the United States (USP) and the European Pharmacopeia (EP). Inbuilt security functions including user authentication and audit trail, support compliance with regulations such as FDA 21 CFR Part 11. The LabSolutions software platform provides integrated management of the measurement data together with data and electronic signature functions (ER/ES) from laboratory TOC analysers and other analytical instruments.
