Maximum performance on a MICRO foot print The Dumas combustion method has become the worldwide used standard for accurate and fast determination of nitrogen e.g. in agricultural products. Compared to the wet chemical Kjeldahl method it is superior in terms of speed, safety and environmental friendliness. The representative analysis of a natural product requires a larger sample size of up to 1 gram or more. ELEMENTAR in Germany has been the pioneer in the development of analyzers not only for organic elemental analysis, but also in the analysis of macro sized samples. ELEMENTAR introduced the macro N analyzer in 1988. It was the world’s first combustion type nitrogen analyzer for samples up to 3 g using reusable steel crucibles. This was followed by the famous vario MAX family, a complete line of macro analyzers for N, CN, CNS or CHN determinations. The vario MAX cube N/CN is the next generation of ELEMENTAR’s continuing line of macro analyzers. The longest tradition in macro analyzer design combined with state of the art electronics, software and robotics has made the vario MAX cube the leading analyzer in terms of analytical performance, reliability, cost and speed of analysis. Largest sample size up to 3 g mass for N and CN analysis. Up to 330 mg absolute N or 500 mg C content can be measured. 90 position autosampler for 4 ml stainless steel sample cups for solids and liquids with virtually unlimited life. No liquid spillage, no liners. Automatic ash removal and rechargeable at any time also during operation. Highest speed of analysis less than 4 min for N (sample to sample). High sample throughput is realized without interruption by frequent blank and recalibration measurements. Best precision e.g. of 5 ppm N in beer or 10 ppm C in soil. Extreme long time stability for unattended, fully automated overnight operation. Only one blank value check is required per day. Efficient water removal a multistep condenser and Nafion® gas dryer results in long time maintenance free operation, even for continuous series of 2 mL aqueous samples.

vario MAX cube Lowest cost per analysis due to drastically reduced gas consumption, use of stainless steel reaction tubes and lower cost, longer lasting reagents. Minimal maintenance requirements e.g. no need for soot filters or CO2 scrubbers, no ballast tank cleaning, no heater replacement or other frequent exchanges and inspections. No. 1 in reliability vario MAX is known as a synonym for reliability, but vario MAX cube has even been further improved. Proven robust construction, 10 years guarantee for furnace and detector results in very long lasting operation. Elementar also guarantees...
