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 TOC analyzers continues. The Dohrmann Series Fusion Total Organic Carbon Analyzer is no exception. The Fusion 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 Analyzer utilizes powerful UV Persulfate oxidation allowing superior carbon liberation from even the most challenging matrixes. By implementing the patented Static Pressure Concentration (SPC) technology, the Fusion Total Organic Carbon Analyzer is able to achieve unprecedented low-end sensitivity from a Non-Dispersive Infrared (NDIR) detector. The Fusion Analyzer is built on the latest technology and is designed to offer productivity for a wide variety of applications.​

NDIR Pressurization Overview

Pressurized detection, or static read, is a technique used for concentrating the CO₂ produced by the oxidation of the sample. The technique can be used for both qualitative and quantitative analysis. In this section the basics of the pressurization technique will be described. Click for more on NDIR Pressurization Overview​.
