UNICUBE utilizes Elementar's proprietary and improved direct Temperature Programmed Desorption (direct TPD) technology for highest reliability and performance in gas separation. In combination with the most powerful detector in the market, the instrument is capable of determining samples with C:N and C:S elemental ratios of up to 12,000:1. HIGH-TEMPERATURE COMBUSTION All elemental analyzers from Elementar are designed for minimal sample preparation and secure, unattended 24?/?7 operation. They use the safe, simple and environmental friendly high-temperature combustion principle. The proven Elementar double furnace technology with separated combustion and reduction zone ensures longest maintenance intervals. In combination with an efficient, active oxygen dosing, it guarantees quantitative conversion of the sample to measuring gas — a prerequisite for highly precise and matrix-independent elemental analysis. DIRECT TEMPERATURE PROGRAMMED DESORPTION (DIRECT TPD) UNICUBE uses the proprietary direct TPD technology to chromatographically separate the combustion gases prior to detection in a highly sensitive thermoconductivity detector. The temperature program for the gas separation is controlled by a sensor positioned on the inside of the direct TPD column - directly in the gas stream. This setup has unique benefits such as very sharp peaks through direct control of the gas desorption temperature and guaranteed baseline separation of all gases - even for extreme elemental ratios. This makes the direct TPD technology capable of resolving C:N and C:S ratios of up to 12,000:1. The distinct peak separation assures absolutely reliable and trouble-free data acquisition. Elementar’s unique direct TPD columns are optimized to provide unmatched robustness and longevity compared to classic GC columns. * Temperature Programmed Desorption ** Thermoconductivity Detector Reliable results UNICUBE guarantees outstanding precision and accuracy through quantitative combustion via oxygen jet-injection directly into the combustion zone. This leads to matrix- independent results even for samples which are di?cult to combust. In combination with the state-of-the-art thermoconductivity detector, the instrument can provide an elemental detection limit down to < 50 ppm. Ease of use UNICUBE is optimized to simplify daily routine operation. Clearly arranged, easily accessible system components as well as a furnace that slides out minimize maintenance and maximize uptime. The tool-free clamp connection system ensures a reliably leak-tight instrument at any time. Thus, users can enjoy smooth analyses and confidence in their results. Thanks to a novel self-regulating cooling air circulation, UNICUBE becomes the quietest elemental analyzer in its class. A low noise level - not louder than falling rain - makes working with UNICUBE pleasant to your ear.
