| titleOfInvention | A Flow System Polycyclic Aromatic Hydrocarbon Fluorescence Detector and Its Application |
| abstract | The patent of the present invention provides a flow system polycyclic aromatic hydrocarbon fluorescence detector. Amplifier circuit composition. The deep ultraviolet LED can excite 15 kinds of polycyclic aromatic hydrocarbons to emit fluorescence; the colored absorption glass is used to strongly absorb the stray light in the deep ultraviolet band; the emission filter has an ultra-broad spectrum, covering the emission spectrum of 15 kinds of polycyclic aromatic hydrocarbons. The invention uses deep ultraviolet LED instead of xenon lamp as light source, photodiode integrated amplifier circuit instead of photomultiplier tube (PMT) as detector, without wavelength adjustment (baseline has no step rise or fall), can simultaneously detect 15 kinds of multi-rings with high sensitivity Aromatic hydrocarbons, the detection limit of p-benzo(a)pyrene is less than or equal to 0.05ppb. Compared with the prior art, the detector of the present invention has the advantages of long service life, good stability, small size and low cost. |
