CHNS Analyzer

Great sample flexibility thanks to direct Temperature Programmed Desorption (direct TPD) technology

Through the use of our direct TPD technology, which stands for highest reliability and performance in gas separation, and in combination with the most powerful detector on the market, the UNICUBE offers great sample flexibility. The direct TPD technology guarantees a large dynamic measurement range, enabling the analysis of samples with C:N and C:S elemental ratios of up to 12,000:1 with reliable baseline separation. This allows for the analysis of homogenous substances of small sample weights (0.1 mg) as well as the analysis of inhomogeneous samples up to 1 g. The UNICUBE can analyze samples with a maximum carbon content of 14 mg (50 mg in CN mode) and offers optional upgrade kits for the determination of sulfur via infrared detector, oxygen, and chlorine.

Reliable results due to blank-free sample introduction and jet-injection of oxygen

UNICUBE offers analysis results with highest precision and accuracy. This is due to our patented ball valve sample introduction, which introduces samples blank-free into the analyzer. This is especially beneficial to trace nitrogen analysis. Furthermore, the jet-injection of oxygen directly to the point of combustion and the high furnace temperatures of up to 1,200 °C ensure a complete conversion of the sample to measuring gas –  a prerequisite for highly precise, matrix-independent elemental analysi
