TOC 1080 Analyzer

1080 TOC Analyzer — Product Overview

The 1080 Total Organic Carbon (TOC) Analyzer from OI Analytical delivers high-accuracy carbon measurement for a wide range of water matrices — from drinking water to industrial wastewater. Designed to handle even the most challenging samples, the 1080 combines robust high-temperature catalytic oxidation, advanced detection technology, and low-maintenance engineering to provide reliable performance with minimal downtime.

With over 45 years of TOC innovation, OI Analytical has engineered the 1080 to meet the needs of modern environmental, industrial, and municipal laboratories seeking dependable TOC analysis at a lower cost of ownership.

Key Applications

The 1080 TOC Analyzer is ideal for analyzing:

  • Potable (drinking) water

  • Municipal wastewater

  • Industrial wastewater

  • Sewage effluent

  • Sea water

  • Groundwater and surface water

Approved / Supported Methods

The instrument fully supports major regulatory and international methods, including:

  • USEPA 415.1 – Drinking Water

  • Standard Method 5310B – Wastewater, Ground & Surface Water

  • USEPA 9060A

  • USEPA DBPR (Disinfection Byproduct Rule)

  • ISO 8245 – Drinking Water, Wastewater

  • EN 1484 – Surface & Ground Water, Potable Water

  • ASTM D7573-09 – Water, Wastewater, Sea Water

Technology & Performance

High-Temperature Catalytic Oxidation (HTCO)

The 1080 uses high-temperature catalytic combustion at 680°C to oxidize organic compounds into CO₂, which is then detected using a solid-state non-dispersive infrared detector (SS-NDIR).

This technique ensures:

  • Excellent oxidation efficiency

  • Long-term stability and accuracy

  • Reliable performance even with high-salt or particulate-rich samples

Patented Catalyst Protection

Unique design features protect the catalyst and combustion system, significantly reducing:

  • System wear

  • Plugging

  • Maintenance costs

  • Instrument downtime

Automatic Sample Handling

Built-in automation includes:

  • Sample acidification

  • Sparging

  • Automatic dilution

  • Automated cleaning of sample pathways

These features ensure accurate results across diverse matrices, including difficult samples containing humic acids, salts, or complex organics.

Autosampler Compatibility

Paired with the Model 1088 Autosampler, the system supports:

  • Up to 88 samples per batch

  • Walk-away automation

  • Priority samples without stopping the run

  • A compact bench footprint (autosampler fits directly under the analyzer)

Advantages

  • High performance on even the toughest samples

  • Low cost of ownership

  • Robust design for long-term reliability

  • Easy maintenance and fast service access

  • User-friendly operation and clear TruColour™ LED status indicators

  • Optional TNb (Total Nitrogen) measurement module — no ozone required
