- Sensitive – detection limit of 10 mg/kg
- Unfailing – 10 years warranty on furnace and detector
- Unique – Carbon and nitrogen determination at trace levels
Matrix independent determination of N and C at trace levels
UNICUBE trace sample digestion is carried out by catalytic combustion at a temperature of 950 °C, the nitrogen and carbon containing components in the sample form a mixture of different oxides and N2. The resulting gases then pass through the reduction tube, where carbon compounds are safely reduced to CO2 and nitrogen compounds to N2. After removal of other combustion products like H2O and SO2, CO2 and N2 are measured by thermal conductivity detection.
The system is designed for easy, low maintenance operation; matrix independent analysis allows the use of a standard ‘universal’ calibration for any sample type. The front door of the analyzer opens to give excellent access for replacement of consumables exchange of combustion and reduction tube is particularly easy due to the slide out furnace.
Elementar gives a 10 year warranty on both the furnace and thermal conductivity cell, thus emphasizing the stability of the system.
