TOC analyzers from Elementar based on catalytic high-temperature combustion have been providing remarkable performance in environmental and wastewater laboratories for decades. Now the innovative enviro TOC combines proven functions with new technologies: the powerful furnace, variable mode changes, real matrix separation with SALTTRAP and the stable, wide-range IR are complemented by a completely new autosampler system and a novel chemiluminescence detection system. This makes enviro TOC the ideal, future-oriented instrument for flexible and efficient TOC and TNb determination in environmental and wastewater samples.

Fully-automated, 60-position sampler with rinsing function. Optional autosampler for solid samples. Integrated TNb determination with ECD or CLD. Clearly-arranged, easily accessible components enable fast and easy maintenance.

TOTAL ORGANIC CARBON (TOC)

The analysis of TOC in wastewater to assess organic contamination or to evaluate the cleaning efficiency of sewage treatment plants is an international standard procedure. Also, TOC and TNb determination are indispensable for monitoring organic pollution and nitrogen load in surface waters. The enviro TOC is tailored to the analysis of TOC, NPOC, TC, TIC, DOC, POC or TNb in these matrices. Samples are injected with a 60-position autosampler. Integrated rinsing functions minimize carryover during the analysis of particle-containing samples. In addition, the measurement of soil samples or waste is also possible without time-consuming instrument modifications. As one of the few analyzers on the market, enviro TOC offers fully automatic TOC determination in solid and liquid samples with one system.

Flexible nitrogen determination

The enviro TOC enables simultaneous TNb determination either using the proven EC cell technology or a novel, integrated chemiluminescence detector (CLD). The innovative CLD concept provides stable conditions for NO measurement in the carrier gas. Consequently, the NO signal is linearly correlated with the TNb concentration over a large measurement range. The built-in CLD does not require additional laboratory space and delivers extremely stable values, which simplifies calibration as well as result evaluation.

Real matrix separation with SALTTRAP

During the combustion of salt-containing samples, 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, thus saving running costs during operation. 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.

High-temperature combustion

In compliance with international standards, the TOC has to be oxidized at temperatures > 680 °C. The temperature range from 680 °C to 750 °C is ideal for the combustion of samples with a high salt load. In addition, temperatures up to 1200 °C ensure optimal oxidation conditions and excellent recovery even of highly stable compounds such as humic or fulvic acids or samples containing particles, respectively. The robust furnace of the enviro TOC with its flexibly adjustable temperatures covers all these requirements and guarantees a complete oxidation. However, reliable carbon analysis of waste or carbonates often requires higher temperatures. Consequently, in solids mode operation of the enviro TOC, the combustion enthalpy of the tin capsules ensures a temperature increase up to 1800 °C.

TOC / TNb analysis has never been easier!

In Accordance with Official Standards

The enviro TOC works in compliance with all relevant standards for TOC, TC, TIC and TNb in liquid samples such as ISO 20236, ISO 8245, EN 1484, EN 12260, SM 5310B, EPA 415.1, and ASTM D7573. Due to the unique solids option, TOC and TC can also be determined in solids like soil or waste according to EN 15936 and ISO 10694.

Easy and cost-effective maintenance

The user-friendly maintenance concept of the enviro TOC ensures the most efficient routine analysis: Our goal is that the maximum lifetime of the instrument can be reached with minimum maintenance effort. Consequently, all consumables can be easily replaced by the user. Clearly arranged, easily accessible components guarantee that most maintenance work can be carried out independently within a very short time. This saves running costs and avoids downtime of the instrument.
