The nitrogen–phosphorus detector (NPD) is also known as thermionic specific detector (TSD) is a detector commonly used with gas chromatography, in which thermal energy is used to ionize an analyte. It is a type of flame thermionic detector (FTD), the other being the alkali flame-ionization … See more A concentration of hydrogen gas is used such that it is just below the minimum required for ignition. A rubidium or cesium bead, which is mounted over the nozzle, ignites the hydrogen (by acting catalytically), and … See more • Gas chromatography See more Web-Flame thermionic detector (FTD) uses a heated alkali metal compound -Analytes are ionized by the extraction of the electrical charge from alkali metal surface -Ions are produced when the analytes are burned in a flame. f TYPES OF DETECTOR • Mass detector • Independent of carrier gas flow • Destructive SELECTIVITY • Highly selective
