Now, we have used our technical know-how to take our proven micro elemental analyzer, theUNICUBE® Micro combustion analysis has never been easier. Making 'good' even better: as a leader in elemental analysis technology, our products benefit from having more than 120 years of experience behind them. Now, we have used our technical know-how to take our proven micro elemental analyzer, the vario MICRO cube, to the next level - always focusing on the needs of the users.
The result is the new UNICUBE, a cutting-edge tool for the elemental analysis of carbon, hydrogen, nitrogen, and sulfur. UNICUBE combines the low costs and the sensitivity of a micro elemental analyzer with the flexibility and outstanding robustness of a macro analyzer, providing unparalleled flexibility.
- One micro elemental analyzer for all tasks: 0.1 mg of pharmaceuticals can be analyzed just as precisely as up to 1 g of inhomogeneous soil samples, while volatile gasoline or temperature-proof silicon carbide can be analyzed just like coal, foodstuffs, or sewage sludge. UNICUBE makes this possible without any restriction of the elements, allowing simultaneous analysis for CHNS - or for the combinations CNS, CHN, CN, O, and Cl - in one sample run.
- High-performance micro elemental analysis for the sharpest peaks: UNICUBE utilizes Elementar's proprietary and improved direct TPD (Temperature Programmed Desorption) technology for optimized reliability and performance in gas separation. Working in combination with the most powerful detector on the market, this means the instrument is capable of determining samples with C:N and C:S elemental ratios of up to 12,000:1.
- Quiet operation: Thanks to its novel self-regulating air circulation cooling system, UNICUBE is the quietest elemental analyzer in its class. A low noise level - no louder than falling rain - makes working with UNICUBE pleasant to the ear.
- Smart design for optimal ease of use: Maintenance can be minimized and uptime maximized thanks to UNICUBE's clearly arranged and easily accessible system components, as well as its slide-out furnace. The tool-free clamp connection system ensures reliable leak-proof operation at all times, meaning users can enjoy smooth analyses and full confidence in their results.
- Quantitative high-temperature decomposition: UNICUBE functions at a permanent temperature near 1,200°C, reaching 1,800°C during combustion. In pure oxygen, the contained sulfur is fully converted into SO2 with a 100% recovery, even in the case of BaSO4. Carbon is converted to CO2 and detected by a real non-dispersive IR photometer.
- Large dynamic concentration range: UNICUBE's measuring range is 0-100%, or 20 mg S absolute, with just one IR detector and sensitivity range. The measuring range for carbon is 0-100%, or up to 40 mg absolute. Even concentrations of below 1 ppm or 0.2 µg S can be detected.
- Large weighing range: UNICUBE's range encompasses micro (< 1 mg) and macro (1 g) applications, depending on the sample type.
- Direct Temperature Programmed Desorption (direct TPD): The system's direct TPD technology allows gaseous components to be separated perfectly with an optimized TPD column without peak overlap. Time per analysis is also optimized automatically.
- Multipoint calibration: UNICUBE offers reliable stability over months and matrix-independent functionality.
- Instrument parameters are PC-controlled via Windows or Linux: The whole instrument is digitally controlled and can also be operated via the internet, with a 21 CFR Part 11 option for data safety. Because the system is fully digitized, it can be operated remotely.
- One high-performance instrument for all applications: UNICUBE operates without expensive special catalysts, with easy ash removal from the combustion tube and an extended lifetime for all components, helping to ensure a low cost of ownership.
- Clean, safe, fast: The analysis only takes a few minutes, with no aggressive or toxic chemicals required. Helium is used as a carrier gas, or argon as a possible alternative.
- Easy installation requirements: The system takes up a minimal 48 x 55 cm benchtop space, operating with a single power supply (230, 110, 100 V), and two gases sufficient for maintenance-free long-term operation.

TOC Analyzers from Elementar based on catalytic high-temperature combustion have been providing support to environmental and wastewater laboratories for decades. Now Elementar’s new TOC/TNb analyzer, enviro TOC, combines the technical know-how of its predecessor, the vario TOC select, with innovative 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.
- Designed for environmental samples
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.
- TOC analyzer with 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.
- 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.
- Analysis methods
High-temperature catalytic carbon oxidation up to 1200 °C and CO2 detection with NDIR for TOC, NPOC, TC, TIC, POC (VOC), DOC. TNb determination simultaneously with CLD or EC cell (option).
- Innovative detectors
Customized, integrated detectors for CO2 and NO determination. Variable sample volumes allow multipoint calibration from a single standard solution and avoid dilution errors. Extraordinary linearity over a large calibration range.
- Modular concept for liquids and solids analysis
Automatic 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
The innovative combustion tube concept enables real matrix separation and offers maximum protection of the combustion tube. Designed for analyses of salt-containing samples, particles or other complicated sample matrices.
- Software with high performance and maximum flexibility
Instrument control with a Windows standard PC, control and evaluation software with flexible calibration features, advanced math operations, and intuitive troubleshooting. Integrated maintenance software and comprehensive help menu.
- Robust furnace
Working temperatures up to 1200 °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.
- Easy, compact, economical
The unique instrument concept is characterized by easy handling and optimized for low maintenance costs – with high flexibility and analytical performance.
