flame photometric detector
This light is detected by a photomultiplier tube. Turns the glow plug. Pin On 教育 Further the radiation is specific for each element so simple detectors are sufficient for the purpose of photovoltaic cells phototubes etc. . The flame photometric detector FPD allows sensitive and selective measurements of volatile sulphur and phosphorus compounds. The unit described here uses narrow bandpass interference filters for spectral isolation of the phosphorus emission at 526 mµ and sulfur emission at 394 mµ. Turns all detector gasesair hydrogen makeupoff. The detection principle is the formation of excited sulphur S 2 and excited hydrogen phosphorous oxide species HPO in a reducing flame. An FPD uses a hydrogenair flame into which the sample is passed. Flame Photometric Detector FPD for GC.
