Agilent 255 Nitrogen Chemiluminescence Detector (255 NCD) Product Information
The Agilent 255 Nitrogen Chemiluminescence Detector (255 NCD) is designed to easily detect organic compounds containing nitrogen. It achieves this by converting the compounds into nitric oxide using a stainless steel burner that operates in a hydrogen and oxygen plasma at temperatures greater than 1800 °C.
The detector utilizes a red optical filter to transmit light from the chemiluminescence reaction while suppressing signals from other chemical species. This selectivity ensures that major constituents of sample matrices, such as carbon dioxide, water, nitrogen gas, and noble gases, do not interfere significantly with the determination of trace levels of nitrogen-containing analytes.
