High Temperature Combustion TOC – Tekmar Torch

Tekmar’s newest addition to the TOC analyzer product line, the Torch, utilizes a patent pending Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion.

The Torch Analyzer contains a built in autosampler with three vial rack choices and PC driven control. This features automated calibration and Intellidilution which automatically dilutes over-range samples to within the working calibration range. Maintenance is simplified by design allowing easy access to all areas of the unit.

All of these features and competitive price positioning make this system ideal in keeping costs down and maintaining productivity in the laboratory.

UV – Persulphate TOC – Tekmar Fusion

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.
