TOC Fushion UV/Persulfate – Total Organic Carbon Meter

Nearly 40 years ago, Dohrmann began designing and manufacturing the premier Total Organic Carbon (TOC) Analyzer. Since joining the Tekmar family, the tradition of producing innovative laboratory TOC analyzers has continued. The Fusion Dohrmann series organic carbon analyzers are no exception. The Fusion TOC analyzer offers greater flexibility, intelligence and user-friendliness, making it ideal for the most demanding laboratory needs.

The Organic Carbon (TOC) Analyzer and TekLink™ Software provide solutions to increase sample throughput while improving the reliability of analytical data. Some of the features that increase ease of use are:
  • Unattended automatic calibration monitoring
  • Possibility of automatic dilution from master or sample standards
  • Intellidilution to automatically dilute the sample back to the calibration range.
  • Automated self-diagnostic tools including leak testing
  • 21 CFR 11 Functions – Electronic Records and Electronic Signatures (ERES) including user account management and audit trails
  • Reports can be exported in user-defined formats including metadata and versions
  • Develop a “turnkey” approach (use it now) and build a schedule
  • Massive Flow Controller (MFC) for reduced gas consumption and advanced flow control
