Velp Carbon Nitrogen Analyzer

Productive
Flash determination of carbon and nitrogen content
Determination of TC, TOC (after acidification), TIC, TN and Carbon/Nitrogen Ratio
Automated analysis of preloaded samples (117 positions)
Totally unsupervised operation
Results produced 24/7/365

Precise
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

Versatile
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

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