TOC analysis of environmental water and wastewater at its best

The enviro TOC is an innovative, future-oriented instrument solution for TOC/TNb analysis, customized for environmental and wastewater samples. Our TOC analyzers based on catalytic high-temperature combustion have been providing remarkable performance in environmental and wastewater laboratories for decades. The enviro TOC combines the technical know-how of its predecessors with innovative technologies. The analyzer addresses the needs of any environmental and wastewater laboratory facing a wide sample matrix including solids, precise results and high sample throughput.

Highlights of the enviro TOC

Highest sample flexibility

for liquid and solid samples, as well as particle containing samples thanks to the powerful combustion at up to 1,200 °C

Highest sample throughput

through the autosampler, parallel rinsing and measurement functions and the easy-to-use lyticOS® instrument software

Negligible carryover and precise results

thanks to the autosampler with integrated rinsing functions

Long lifetime & low running costs

due to the unique SALTTRAP matrix separation

It's time to TOC - TOC vs. BOD & COD


Learn why total organic carbon (TOC) measurement is the safer, more reliable and environmentally friendly alternative to biological and chemical oxygen demand (BOD and COD) measurement in wastewater analysis in this white paper.

Wide sample matrix for environmental samples

The enviro TOC is tailored to the analysis of TOC, NPOC, TC, TIC, DOC, POC or TNb in environmental matrices. As one of the few analyzers on the market, enviro TOC offers fully automatic TOC determination in solid and liquid samples within one system. The high temperature combustion furnace with temperatures up to 1,200 °C guarantees a complete oxidation and recovery of even stable carbon compounds. In comparison to other techniques for the determination of organic contamination, the use of hazardous substances is avoided and the analysis time is only a few minutes.

Highest sample throughput thanks to intelligent instrument design

The high-throughput 60-position autosampler for 40 ml EPA vials ensures convenient processing of samples and offers unattended 24/7 routine operation. The intelligent lyticOS instrument software enables parallel rinsing and measurement, which saves time and increases the sample throughput. Furthermore, the intuitive user interface of lyticOS makes the operation, the control and results evaluation incredibly easy. In combination with the user-friendly maintenance concept, the enviro TOC ensures the most efficient routine analysis with minimum maintenance effort.

Negligible carryover and precise results

The fully automated 60-position autosampler of the enviro TOC offers integrated rinsing functions, which avoid carryover and sedimentation of particle containing samples. This leads to accurate and precise analysis results as well as longer lifetime of the affected instrument components.

Long lifetime & low running costs with SALTTRAP matrix separation

During the combustion of salt-containing samples, the salts crystallize in the combustion tube. If the crystallization occurs directly on the quartz glass or in the catalyst, their lifetime is significantly reduced. The unique SALTTRAP of the enviro TOC guarantees user-friendly maintenance intervals of the combustion tube and the catalyst even for concentrated salt solutions. This leads to significantly reduced running costs. Depending on the nature of the salt, a slight decrease in crystallization can be achieved by reducing the combustion temperature. However, only SALTTRAP guarantees truly effective glass corrosion protection because the salts are trapped directly at the point where they melt.

Future-proof thanks to 10 years guarantee

Thanks to the outstanding longevity and robustness of our enviro TOC, we grant a 10-year guarantee on the high-temperature combustion furnace. With our long-term oriented dedication to technical support, we provide spare parts for a minimum of 10 years. This results in outstanding low total cost of ownership, giving you confidence in return of investment.

Product details

The enviro TOC is optimized for environmental and wastewater analysis. The following modes are available:

  • Liquid mode

The liquid mode offers a fully automated 60-positions autosampler. All positions can be stirred, automatically acidified, and purged. Alternatively, a cost-efficient solution with manual sample change is also available. The change between liquid mode and solid mode is very easy and takes only a few minutes.

  • Solid mode

The solid mode offers different autosamplers for up to 120 sample positions. Alternatively, a cost-efficient solution with manual sample change is also available. The change between liquid mode and solid mode is very easy and takes only minimum time.

Analysis method

High-temperature catalytic carbon oxidation up to 1,200 °C and CO2 detection with IR detector for TOC, NPOC, TC, TIC, POC (VOC), DOC. TNb determination simultaneously with CLD or ECD (option).

Robust furnace

Working temperatures up to 1,200 °C. Suitable and flexible temperature settings for salt-containing solutions (~720-750 °C), particle-containing solutions (850 °C), and solids (> 900 °C) with one furnace.

Autosampler for liquids

Fully automated, 60-position autosampler for 40 ml EPA vials for liquids, fully integrated into the instrument. All positions can be stirred, automatically acidified, and purged. Septa are available. Alternatively, cost-efficient solution with manual sample change. Quick and easy exchangeable with solids sample feeder.

Modular concept for liquids and solids analysis

Automated sample feeders for liquids and solids, alternatively cost-efficient solutions with manual sample change. Quick and easy exchangeable. Can be upgraded at any time.

SALTTRAP ensures low maintenance for salt-containing samples

The innovative combustion tube concept enables real matrix separation and offers maximum protection of the combustion tube. Leads to long lifetime and low running costs. Designed for analyses of salt-containing samples, particles, or other challenging sample matrices.
