CN 802 Carbon Nitrogen Elemental Analyzer

The CN 802 enables analysis across a wide range of sample types, including solid, semi-solid, and liquid samples.  

It accommodates large weights and volumes, and it is suitable both for inhomogeneous samples and those with low concentration levels.  

The CN 802 ensures high-precision results and excellent reproducibility with: 

• A carbon limit of detection ranging from very few ppm to 150 mgC; 
• The lowest LOD for Nitrogen; 
• A relative standard deviation (RSD) lower than 0.5% (EDTA).

Capable of processing up to 117 samples at a time, the VELP C/N elemental analyzer boasts exceptional efficiency, enabling the highest sample throughput. This is made possible by the electronic autosampler and balance connection to the PC for direct weighing data transfer.   

Laboratories have the option to select between Helium and Argon as the carrier gas. Additionally, with dedicated accessories, kits, and tin cups, you can easily analyze liquid samples with high sensitivity and accuracy.

The sample is purged with a carrier and drops down into the combustion reactor where it is converted into its elemental compounds at a high temperature (above 1000°C).  
 
Water separation is performed in 2 steps. The combustion gases are carried to the first maintenance-free physical trap DriStep^TM (WT1), strategically placed after combustion, trapping 99% of water. Secondly, a chemical trap (WT2) ensures complete removal of the remaining 1% of water. 
 
The combination of high temperature and the exclusive Vcopper^TM reduces nitrogen dioxide to molecular nitrogen inside the reduction furnace.
 
The VELP HighSensIR detector enables analysis of an extremely wide carbon concentration range, from just a few ppm up to 150 mg of absolute carbon, from micro to macro applications.  
 
Then, Auto-regenerative CO2 absorbers trap carbon dioxide, allowing the exclusive TCD (Thermal Conductivity Detector) to detect the Nitrogen content.
