Demands for highly purified water and its quality control are getting stronger in many industries, such as pharmaceutical, medical device, food/beverage, chemical, precision machinery, and semiconductor. Shimadzu's eTOC product lineup has been designed to satisfy this demand. The TOC-1000e is the first Shimadzu eTOC. It has very high sensitivity and low detection limits, reaching 0.1 µg/L, making it perfectly suitable for ultra-pure water measurement. Technology, Usability, and Reliability: the defining attributes of the ultra-small, high-value eTOC.

A first in technology providing the smallest and lightest instrument casing *1

The first TOC analyzer in the world to use a mercury-free excimer lamp *2

The excimer lamp emits high-energy 172 nm wavelength light by inducing a dielectric barrier discharge within a xenon gas. The TOC-1000e is the first TOC analyzer in the world to use a mercury-free excimer lamp. The TOC-1000e also features new “Active-Path” technology for transferring energy from the lamp to the sample. It efficiently irradiates the sample inside the lamp with ultraviolet light to reliably oxidize organic matter. This new Shimadzu technology achieves both high measurement performance and high environmental performance.

Problems with Typical TOC Analyzers


Large indicator and display screen on a small cabinet

A smart user interface and the large touch-panel screen provide exceptional visibility and operability. The indicator clearly shows the analyzer's status, such as standby, measurement in progress, or active warning. The large display screen provides properly visibility to confirm data and perform operations.

Small, lightweight casing provides installation flexibility

The small and lightweight TOC-1000e 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 flexibility to choose the most convenient location for installation.

TOC-1000e Mounting Options

Easy-to-use and maintain design improves efficiency

One-year maintenance-free.*3 Tool-free maintenance.

The simple configuration is designed to be maintenance-free for a year.*4 The only parts that need to be replaced during regular maintenance are the excimer lamp and pump head. Both parts can be accessed via the front door of the analyzer and easily removed or installed without any tools.

Onsite calibration/validation using a vial sampler
Certified standard solutions are available

Using an optional vial sampler, the analyzer can be calibrated or validated at the operating site. The sampler can hold four standard solutions for creating up to four-point calibration curves. Certified standard solutions, which are suitable for calibration, validation, or system suitability test, are available. The sampler and the certified standard solutions make calibration and validation easier and more reliable.

Print Output

The TOC-1000e can export data to a printer (optional).
For information about compatible printers, please contact a Mandel representative.

External Input/Output

By using an external input/output kit (optional), measurement values can be exported as an analogue output (4 to 20 mA) or a contact output to notify the user of measurement results, alarms or events.

View/Acquire data from a web browser through the network

By connecting TOC-1000e to a network, results can be checked remotely from the web browser of a PC or tablet. No special software is required. Data can also be downloaded as a file. Even if there are multiple analyzers in different locations, routine checking can be carried out from one place.

Reliability to support regulations

Measurement reliability supports regulatory compliance requirements

The UV oxidation-conductivity method enables highly sensitive measurements with a simple analyzer design. The system achieves high sensitivity with a detection limit of 0.1 µg/L, which is suitable for ultra-pure water quality control. It is also compliant with the pharmacopoeia requirements of various countries, such as the USP and EP.

User authentication and access rights control

Users can be authenticated based on an ID and password. User access rights are controlled according to four user levels: “Administrator”, “Main User”, “User”, or “Guest”.

Operation/Event log

All operations performed by operators, measurement value alarms, instrument errors, and other operating events are recorded. Filters by "Category", such as "Measurement Alarms" or "Instrument Errors", can be applied for browsing the log history. Descriptions and reasons for frequently performed operations can be registered in advance and then recalled later.

Integrated data management

A daily report summarizing measurement results from each day and an operation log can be exported daily to a LabSolutions database via a network. Data from multiple TOC-1000e analyzers and data from other analytical instruments can be managed centrally together.
