Elementar unicu-trace-120 200009342

The UNICUBE trace is an organic elemental analyzer for highly sensitive carbon and nitrogen determination in solid and liquid samples using high-temperature Dumas combustion and a thermal conductivity detector (TCD). It performs fast trace-level CN or N analyses with a detection limit of 10 µg/g (10 ppm) and is optimized for unattended, high-throughput workflows including automated sample introduction via a 120 position autosampler. Typical use cases include trace carbon and nitrogen quantification in environmental, soil, sediment, and other laboratory sample matrices where matrix-independent, low-level CN measurement is required.

Key Features:

• Detection limit: 10 µg/g (10 ppm) for carbon and nitrogen
• Typical analysis time: approximately 5 minutes per sample
• Integrated autosampler: 120 positions (reloadable during analysis)
• Combustion furnace temperature: up to 1,200 °C (briefly up to 1,800 °C with tin foil)
• Thermal conductivity detector (TCD) optimized for C and N; direct TPD chromatography for separation
• Dimensional footprint: 48 x 55 x 57 cm (L x D x H)
• Required carrier gases: helium and oxygen

Advantages:

• Exceptional trace sensitivity enabling 10 µg/g detection for low-level CN analysis
• High sample throughput with ~5 min cycle time and automated 120-position autosampler for unattended operation
• Blank-free sample introduction and jet-injection oxygen ensure complete combustion and reliable, matrix-independent results
• Long maintenance intervals and robust high-temperature components designed for sustained uptime
