VELP CN 802 Carbon Nitrogen Analyzer

Code Product

CN 802    230 V / 50-60 Hz     F30800090

A versatile and cloud enabled elemental analyzer able to perform precise carbon and nitrogen analysis in 4 to 5 minutes. It is the ideal solution for high throughput offering complete safety to operators.


  • Flash determination of carbon and nitrogen content
  • Determination of TCTOC (after acidification), TICTN and Carbon/Nitrogen Ratio
  • Automated analysis of preloaded samples (117 positions)
  • Totally unsupervised operation
  • Results produced 24/7/365


  • NDIR Detector (Non Dispersive Infrared) to detect Carbon concentration
  • LoGas™ TCD with no reference gas required, for Nitrogen content
  • Unmatched LOD: Carbon 0.01 mgC, Nitrogen 0.001 mg N (using He) or 0.01 mg N (using Ar)
  • RSD less than 0.5% with EDTA standard
  • Conforms to Good Laboratory Practice standard
  • Leak tests (zone or total) ensure optimum performance


  • Operates with Argon and Helium as carrier gas without any hardware modification
  • Preinstalled methods with element selection (C,N and C/N)
  • Controllable from PC by the powerful CNsoft™ software
  • Clear and detailed reporting software
  • Data storable in multiple formats for LIMS or PC


  • Exceptionally low cost per analysis
  • Premium quality consumables
  • Low energy consumption with Stand-by and Sleeping mode
  • Lowest operator costs

Environmentally Friendly

  • Minimum possible waste & residues
  • Optimized life of consumables
  • Incorporates TEMS™ technology*
