CN 802

VELP CN 802 – Designed to work 24/7

Designed to work 24/7, 365 days a year, the CN 802 allows you to load different matrix of solid, semi-solid and liquid samples at the same time. The analyser also provides carbon detection from ppm – 150 mgC, the lowest Nitrogen LOD in the market of 0.001 mgN with Helium and the RSD lower than 0.5% (EDTA) to assure you high precision results and superb reproducibility.

The CN 802 is easy to install and exceptionally compact saving your valuable lab bench space.

Although the autosampler is supplied with a disc of 30 positions this can be expanded to have capacity for up to 117 samples.

 

Key Features

• The selective Non-Dispersive Infrared NDIR detector is maintenance-free and reads only Carbon content
• The LoGasTM TCD works with no reference gas ensuring accuracy and precision
• Very low oxygen consumption
• Has a maintenance-free DriStepTM water trap (a physical trap that removes 99% of water, therefore reducing the cost of chemicals)
• After-sale support package utilising the ERMES cloud platform and a1 envirosciences service contracts.
