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.

CN 802 analyzes samples of up to 1 g, effectively reducing the cost-per-analysis through VELP combustion technology and the use of genuine consumables with extended lifetimes.  

• The maintenance-free, non-dispersive HighSensIR^TM detector ensures consistent performance over time for the analysis of high and low carbon content samples;  
• The CN 802 LoGas^TM TCD works with no reference gas ensuring the lowest gas consumption on the market;  
• The possibility to seamlessly switch to argon prevents helium availability issues; 
• Optimized combustion leads to very low oxygen consumption: when utilizing a pre-installed method, the instrument accurately doses the gas to ensure full sample combustion based on its weight and matrix, saving resources; 
• The DriStep^TM physical water trap not only requires no maintenance but also removes 99% of water without the need for chemicals; 
• The installation of the CN 802 is straightforward, and its compact design saves valuable bench space in your lab.

The combustion technology drastically improves productivity and eliminates the use of chemicals compared to wet chemistry N/protein determination methods.
