Total Organic Carbon Products

​Fusion UV/Persulfate 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 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 ​​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​.

 TOC Reference Standards

​Teledyne Tekmar, in conjunction with ERA, now proudly offers a full suite of certified TOC reference standards for all TOC instrument manufacturers. Additionally, we have consumable items such as "TOC-Free” vials, pre-made acid and persulfate reagents and an extensive cleaning validation product line.  All standards are prepared from NIST traceable or USP certified reference materials and include a certificate of analysis.  A wide range of concentrations are available in both single use and bulk varieties ranging from 40mL vials to 1L bottles.  Standards can be ordered individually or in sets and in most cases, can be shipped the same day as ordered.  Scheduled inventory replacement plans can be created for convenient re-ordering.
