Nitrogen Chemiluminescence Detector (NCD)
The Agilent 8255 Nitrogen Chemiluminescence Detector (NCD) is a nitrogen-specific detector that produces a linear and equimolar response to nitrogen compounds. This is accomplished using a stainless steel burner to achieve high-temperature combustion of nitrogen-containing compounds to form nitric oxide (NO).
A photomultiplier tube detects the light produced by the subsequent chemiluminescent reaction of nitric oxide with ozone. Because of the specificity of the reaction, complex sample matrices can be analyzed with little or no interference.
