TOC Analyzers


Since the relationship between Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and TOC was established in the 1970s, TOC analyzers have become an analytical backbone in many water treatment and quality control laboratories worldwide.

In environmental applications, TOC is an essential environmental parameter used to measure wastewater from municipal and industrial sources.


TOC analyzers can measure:
• Total carbon (TC)
• Total organic carbon (TOC)
• Inorganic carbon (IC)
• Purgeable organic carbon (POC)
• 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

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.


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.
