TOC Analyzers

Total Organic Carbon (TOC)

TOC is a popular analytical technique in water quality testing, as seen in many official analytical methods today. The United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), recognize TOC as a required test for purified water and water for injection (WFI).

Teledyne Tekmar has a long-standing Total Organic Carbon (TOC) brand rapport from Dohrmann going back to the 1960s. Since Teledyne Tekmar evolved from Dohrmann, 5 generations of TOC combustion analyzers and 4 generations of TOC UV/Persulfate Analyzers have been developed for ultimate customer satisfaction. Each generation demonstrates vast technology improvements over its predecessor leading to today’s industry-leading models: the Fusion, the Torch and the Lotix.

Teledyne Tekmar excels in this industry demonstrated through our dedication in resolving customer needs and concerns, and providing cost-effective beneficial products and services.  These focus areas direct our development process and guides our application support to continuously renew our directions and goals.  Because many companies face moderate workforce turnover rates that make easy-to-learn products essential to minimize lead times to productive personnel.  Teledyne Tekmar has taken this to heart by spending significant time designing cutting-edge user interfaces that feel natural and are easy-to-use for the next generation workforce.

TOC Overview

TOC analyzers can measure:

  • Total carbon (TC)
  • Total organic carbon (TOC)
  • Inorganic carbon (IC)
  • Nonpurgeable organic carbon (NPOC)

TOC measurement involves:

  • Oxidizing organic carbon in a sample
  • Detecting and quantifying the oxidized carbon (CO2)
  • Presenting the result in units of mass of carbon per volume of sample
