Nitrogen Chemiluminescence Detector (NCD)

Nitrogen Chemiluminescence Detector (NCD)

The Agilent 255 Nitrogen Chemiluminescence Detector (NCD) is a nitrogen-specific detector that produces a linear and equimolar response to nitrogen compounds based on a chemiluminescent reaction of NO with ozone. Even complex sample matrices can be analyzed with little or no interference.


  • Nitrogen-specific detection for gas chromatography (GC) or supercritical fluid chromatography (SFC)
  • Picogram-level detection limits
  • No hydrocarbon quenching
  • Linear, equimolar response to organic nitrogen compounds
  • Responds to ammonia, hydrazine, hydrogen cyanide, and NOX
  • Tandem NCD and FID operation
  • Redesigned Burner and Detector, the NCD also has a nitrosamines specific configured option
