More than 50 years ago, in 1964, the rapid N saw the light of day for the first time! Based on these experiences the newly developed rapid N exceed is the most economic and innovative nitrogen/protein analyzer according to Dumas. In day-to-day business it performs routine analyses of food or feed up to 1 g sample weight in your laboratory. The rapid N exceed represents the fast, safe and environmentally friendly alternative to the classical Kjeldahl method.
As the most innovative enterprise in the field of elemental analysis, Elementar takes this traditional analytical technology to a new level. This is made possible by a completely new method of reduction of nitric oxides and absorption of excess oxygen in the analysis gas. Due to a defined interaction of reduction and oxidation (patent applied for) used reduction agent will be automatically generated during operation. Thus, a reduction reactor (reductor) can be used for several thousand samples without change or maintenance.
At the same time, Elementar relies on proven technology for the newly developed rapid N exceed:
- CO2 as carrier gas saves the finite resource helium and guarantees stable prices and constant availability
-
• The fastest protein analysis with analysis times of less than four minutes and highest sample throughput in this instrument class
-
• The post-combustion guarantees exact results, independent of any sample matrix
-
• The rapid N exceed never takes a break: it operates 24/7 – 365 days a year

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, 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.

The UNICUBE trace measures low-level nitrogen and carbon concentrations in solids and highly viscous liquids with a detection limit of 10 mg/kg. Its speciality: nitrogen and carbon determination are carried out using the Dumas method, Matrix-independent determination of N and C at trace levels
The UNICUBE trace measures low-level nitrogen and carbon concentrations in solids and highly viscous liquids with a detection limit of 10 mg/kg. Its speciality: nitrogen and carbon determination are carried out using the Dumas method, which involves the removal of interfering gases during reduction and subsequent detection of the target gases using a thermal conductivity detector. As such, the UNICUBE trace is able to combine the benefits of the matrix-independent Dumas method with high sensitivity.
With UNICUBE trace, sample digestion is carried out via catalytic combustion at a temperature of 950°C, with the nitrogen and carbon-containing components in the sample forming a mixture of different oxides and N2. The resulting gases then pass through the reduction tube, where carbon compounds are safely reduced to CO2 and nitrogen compounds to N2. After removing other combustion products like H2O and SO2, CO2 and N2 are measured by thermal conductivity detection.
The system is designed for easy, low-maintenance operation; matrix-independent analysis allows the use of a standard ‘universal’ calibration for any sample type. The front door of the analyser opens to give excellent access for the replacement of consumables - exchanging the combustion and reduction tube is simple, thanks to the slide-out furnace.
What’s more, Elementar provides a 10-year warranty on both the furnace and thermal conductivity cell, thus ensuring that UNICUBE trace can continue delivering a stable and reliable performance for laboratories.... Read More | The art of elemental analysis
