The UNICUBE model from Elementar offers simultaneous carbon, hydrogen, nitrogen, and sulfur concentration analysis in solid and liquid samples with an option for separate oxygen determination. A wide range of samples can be analyzed ranging from organic/inorganic compounds to coal, fuel, sand/soil, ash, etc. It is equipped with Temperature Programmed Desorption (direct TPD) technology which allows a wide range of elemental concentrations and sample weights. The UNICUBE can analyze trace nitrogen, sub-µg sulfur concentrations, and high carbon content.


The key features of CHNSO includes:


    ⦁ Modes: CHNS and O
    ⦁ Weighing range: Large weighing range spanning from micro (< 1 mg) to macro (around 1 g of soil) applications and up to 15 mg of organic matter
    ⦁ Precision: < 0.1 % absolute (homogeneous substance), depending on sample type, analysis mode, and configuration
    ⦁ Analysis time: ≥ 7 min for simultaneous CHNS determination
    ⦁ High-temperature combustion unit: Complete sample digestion at up to 1,200 °C with jet injection of oxygen directly to the sample ensures complete combustion
    ⦁ Purge and trap chromatography via TPD column
    ⦁ Thermal Conductivity Detector (TCD)
    ⦁ 120 position autosampler
