Fusion Total Organic Carbon (TOC) Analyzer ®


Almost 40 years ago, Dohrmann began designing and manufacturing premier Total Organic Carbon (TOC) Analyzers. Since joining the Tekmar family, the tradition of producing innovative laboratory Total Organic Carbon (TOC) analyzers continues. The Dohrmann Series Fusion Total Organic Carbon (TOC) Analyzer is no exception. The Fusion Total Organic Carbon (TOC) Analyzer offers more flexibility, intelligence and user friendliness making this analyzer ideally suited for the most demanding laboratory needs.

Walk-Away Automation and Intuitive Software Control

The Fusion Total Organic Carbon (TOC) Analyzer utilizes powerful UV Persulfate oxidation allowing superior carbon liberation from even the most challenging matrixes. By implementing the patent-pending Static Pressure Concentration (SPC) technology, the Fusion Total Organic Carbon (TOC) Analyzer is able to achieve unprecedented low-end sensitivity from a Non-Dispersive Infrared (NDIR) detector. The Fusion Total Organic Carbon (TOC) Analyzer is built on the latest technology and is designed to offer productivity for a wide variety of applications.

The Fusion Total Organic Carbon (TOC) Analyzer and TekLink Software offer solutions for increased sample throughput while improving the reliability of the Total Organic Carbon (TOC) analysis data. A few of the features that provide increased ease of use are:

  • Built-in benchmark diagnostic check - including leak check
  • Unattended auto-calibration monitoring
  • Automatic diluting capabilities from stock standards or samples
  • Automated self-diagnostic tools
  • 21 CFR 11 functionality - Electronic Records and Electronic Signatures (ERES) including audit trails and user-account management
  • Exportable reports in user-definable formats including metadata and versioning
  • Turn-key method development and schedule builder

SPC Technology for Superior Sensitivity and Performance

During the TOC analysis, organic carbon is oxidized by a powerful, newly designed UV reaction chamber. Carrier gas sweeps the CO2 from the sample to the detector. An exit valve from the detector is closed to capture all the CO2 in one measurement. Then, the CO2 is evacuated from the detector cell. The overall advantage of the SPC detection technology is the fact that the complete TOC reaction is measured at one time within the detector cell. This technique eliminates the inherent error associated with other detector technologies.
