CN 802 Carbon / Nitrogen Analyzer
The CN 802 combustion elemental analyzer is a versatile, cloud-enabled and fully automatic solution for carbon and nitrogen determination in a wide range of applications. The CN 802 offers high performance on both solid and liquid samples, working in accordance to international standards such as AOAC, AACC, ASBC, ISO, DIN, IFFO, OIV, ASTM, EPA.
Key Features
-
RAPID C/N DETERMINATION
The CN 802 performs analysis of both carbon and nitrogen in just 3-5 minutes. The quick start and sleeping mode ensures fast operation set up with possibility of leak test per zone. -
FLEXIBLE
Fully automatic determination of TC, TN and Carbon/Nitrogen Ratio on solid and liquid samples. Determination of TOC and TIC after external acidification -
PRECISE
The NDIR (Non Dispersive Infrared) detector and LoGas™ TCD (Thermal Conductivity Detector) designed by VELP guarantee unmatched precision and unrivaled LOD. -
EFFICIENT
The fully automatic and reliable combustion method of CN 802 together with DriStep™ water trap guarantees moderate cost. The 30-positions disc autosampler expandable with extra 3 discs ensures maximum productivity and uptime. -
VERSATILE
The CN 802 works with solid, liquid and doughy samples of up to 1 gram. Seamless carrier gas selection between Helium and Argon without hardware changes and with no memory effect. -
SMART & SAFE
The CN 802 is easy to use thanks to the user-friendly CNSoft™ software which is equipped with maximum safety control of the instrument. VELP Ermes connection will deliver a new user experience and smart workflows.

CN 802 Analysis Process
-
CF
(Combustion Reactor) Allows complete combustion at 1030 °C in order to convert all of the sample into its elemental substances. -
WT1
(Physical Water Trap) The maintenance-free DriStep™ cooler permits 99% of water to be removed. -
RF
(Reduction Reactor) Enables the elimination of unwanted compounds and oxygen, transforming NOx into N₂. -
WT2
(Chemical Water Trap) Eliminates the residual water. -
NDIR
(Non Dispersive Infrared Detector) Accurately measures the CO₂ concentration that the instrument is able to convert in carbon quantity. -
CO₂
(CO₂ Regenerating Adsorbers) Used to get rid of all the CO₂. Auto-regenerating, maintenance-free system. -
TCD
(Innovative TCD) LoGas™ determines nitrogen content without the need for a reference gas. Maintenance-free.
