1080 Combustion TOC Analyzer

Total organic carbon (TOC) measurement is a well-established technique that provides valuable information about water quality for process control and regulatory compliance. Though high-temperature combustion TOC is very effective for analyzing samples of high molecular weight or containing substantial amounts of salt or difficult-to-oxidize organics (e.g., humic acid), these types of samples are problematic for combustion TOC analyzers. They can clog the instrument, cause catalyst poisoning, and shorten the injector's life, leading to unreliable data, increased catalyst costs, and significant downtime for servicing the instrument.

With over 45 years of experience designing TOC analyzers, OI Analytical brings game-changing technology to combustion TOC analysis for the accurate results you need with a low cost of ownership and unprecedented ease of use and maintenance. Engineered for unsurpassed reliability and simple operation, the Model 1080 Total Organic Carbon Analyzer handles even the most challenging applications without needing expensive additional kits, modules, or unique options.

Superior Technology for Better Results

Ease of Operation

Designed with the operator in mind, the 1080 TOC Analyzer has been carefully engineered to provide an intuitive workflow experience. You can view the instrument status from anywhere in the lab with the TruColour™ LED Indicator.

Low Cost of Ownership

OI Analytical’s newly developed technologies are designed to keep the cost of ownership low by extending the instrument's life and its components.


Critical components, such as the combustion tube, furnace, and consumable parts, are quickly and easily accessed through a side panel, making maintenance simple. When necessary, the catalyst can be packed in minutes to minimize instrument downtime.

Engineered for Performance

Patent-pending technologies protect the catalyst, increase reliability, reduce maintenance and operating costs, and extend the instrument's life.


The 1080 TOC offers automatic sample acidification and sparging. The automatic dilution function reduces sample salinity, acidity, and alkalinity, significantly extending the dynamic range.

Intuitive Software

With intuitive software features, priority samples can be added at any time without interrupting the operation of the instrument. Built-in tutorials further simplify instrument operation.

Test Methods Supported

The high-temperature combustion technique has been approved and adopted in numerous regulatory compliance methods, standards, and norms for water quality testing.
