Integrated TN b determination with ECD or CLD Clearly-arranged, easily accessible components enable fast and easy maintenance Furnace temperatures up to 1200 °C guarantee a complete oxidation and recovery of stable compounds Unique SALTTRAP located within the combustion tube for a long lifetime and low running costs 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 enviroTOC 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 exible and ecient TOC and TN b determination in environmental and wastewater samples. 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. TOTAL ORGANIC CARBON (TOC) The TOC measuring principle of the enviro TOC is based on catalytic high-temperature combustion of the sample in an oxygen stream > 680 °C. Under these conditions, all bound and dissolved carbon is oxidized to CO 2?, which is determined quantitatively with an IR detector. Sample pre- treatment steps, e.g. for removing the inorganic carbon from the sample, are fully automated. The TOC analysis provides easily evaluable results since matrix effects are negligible and the carbon concentration in the sample correlates linearly with the CO 2 signal. In comparison to other techniques for the determination of organic contamination, the use of hazardous substances is avoided and the analysis time is a few minutes. Designed for environmental samples The analysis of TOC in wastewater to assess organic contamination or to evaluate the cleaning eflciency of sewage treatment plants is an international standard procedure. Also, TOC and TN b 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 TN b 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 modifflcations. As one of the few analyzers on the market, enviro TOC o?ers fully automatic TOC determination in solid and liquid samples with one system. 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 signi-cantly 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 eflective glass corrosion protection, because the salts are trapped directly at the point where they melt. Real matrix separation with SALTTRAP The enviro TOC enables simultaneous TN b 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 TN b concentration over a large measurement range. The built-in CLD does not require additional laboratory space and delivers extremely stable values, which simpli-es calibration as well as result evaluation. Flexible nitrogen determination IDEAL SOLUTION FOR • Environmental laboratories • Research institutes • Quality control SAMPLE TYPES • Surface water • Wastewater (influent and effluent) • Groundwater • Waste • Soil Art.-No. 05 005 624, 06?/?2021 A Excellent precision and accuracy through high-performance combustion. Matrix-independent results. Stable calibration. IN ACCORDANCE WITH OFFICIAL STANDARDS The enviro TOC works in compliance with all relevant standards for TOC, TC, TIC and TN b 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. TOC / TN b analysis has never been easier! Simple, fast conversion from liquid to solid operation. Optional nitrogen determination with an integrated CLD or ECD. Automated sample preparation and injection, intuitive calibra- tion and result evaluation. Easy maintenance. Outstanding robustness and lon- gevity thanks to state-of-the-art technology. 10-year warranty on the furnace and IR detector. 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.
