Shimadzu’s New Online TOC-4200 Analyzer

Shimadzu Scientific Instruments has released the TOC-4200, a next generation on-line TOC analyzer with new functionality for expanded applications, upgraded communication methods, enhanced data handling, and low maintenance and running costs.

The TOC-4200 utilizes Shimadzu's proven, industry-standard 680 °C combustion catalytic oxidation method to support analyses from 5 mgC/L to 20,000 mgC/L full-scale.

With a new high-sensitivity kit, the TOC-4200 can measure samples with TOC concentrations from 0 to 1 mgC/L such as underground water, public drinking water, or recovered deionized water from semiconductor manufacturing.

A high-salt sample combustion tube kit increases the period between necessary maintenance by 10 times when measuring seawater or other high salt concentration samples, while a variety of pretreatment units are available to best match a sample’s characteristics.

The TOC-4200 now offers ECO mode to reduce waste by only using carrier gas and operating the sampling pump when it is needed. A carrier gas purification function is installed as standard.

In addition, a multi-functional sample injector allows for a multipoint calibration curve from a single high standard - a function that now only takes minutes, which would previously take a person an hour.

In addition to standard analog and contact outputs, the TOC-4200 web-based monitoring function allows users to monitor data and status from any network-connected computer.

It is also compatible with digital bus standard (Modbus) two-way digital communication to easily control multiple devices over one line.

Users do not have to worry about measurement interruption with the TOC-4200 notification system, which sends alerts when reagent or consumable replacement periods approach.

Upgraded internal storage holds 20,000 measured values, 100 calibration values, and a history of 100 alarms. All data is easily output to USB memory.

Additional usability upgrades include a color LCD touch screen (easily operated with gloves), sleep settings and automatic calibration schedules.
