State-of-the-Art Technology in the Smallest Casing
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 has been designed to satisfy this demand.
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.
World’s first technology in the world’s smallest and lightest*1 casing
World-first*2 TOC analyzer using mercury-free excimer lamp
Excimer lamps emit high-energy 172 nm wavelength light by inducing a dielectric barrier discharge within a xenon gas. The eTOC is the first TOC analyzer in the world to use a mercury-free excimer lamp.
The eTOC 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.

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.
There is no need to squint at a small monochrome screen or go to a separately located monitor or controller to confirm data and perform operations.
Small, lightweight casing provides installation flexibility
The small and lightweight eTOC 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.
Easy-to-use and maintain design improves efficiency
One-year maintenance-free.*1 Tool-free maintenance.
The simple configuration is designed to be maintenance-free for a year.*2
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
Conditioned standard solutions are also 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.
Conditioned standard solutions, which are suitable for calibration, validation, or system suitability test, are also available.
The sampler and the conditioned solutions can make calibration and validation easier and more reliable.

Export data in an easily readable/usable format
The eTOC can output data to a USB flash drive in text (CSV) or PDF format.
■ Text File
Comma-separated values (CSV) or tab-delimited values. Readable with spreadsheet software.
■ Daily Report (PDF file)
Measurement results are listed in a table and shown in a trend graph.
■ Print Output
The eTOC can export values to a printer(optional).
For information about compatible printers,contact a Shimadzu representative.
■ External Input/Output
By using an external input/output kit (optional), measurement values can be exported as an analog 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 eTOCs to a network, you can check results 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.

24-Hour Continuous eTOC Measurement Data of Ultra-Pure Water
It shows that results are stable enough to check the quality of ultra-pure water around 5 µg/L TOC.
Security functionality for supporting data management
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”.
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 eTOC analyzers and data from other analytical instruments can be managed centrally together.
