Abstract
The invention discloses a flame photometric detector for measuring the phosphor-containing compounds and sulfur-containing compounds, and relates to the technical field of substance detection. The flame photometric detector is characterized by comprises a hydrogen flame part and a photometric part; wherein the hydrogen flame part comprises a flame nozzle, a shading groove, and an igniter; and the photometric part comprises a quartz window, an optical filter, and a photoelectric multiplier tube. The flame photometric detector is used to measure phosphor-containing compounds and sulfur-containing compounds. The signals generated by the phosphor-containing compounds and sulfur-containing compounds in flame are almost 10000 times stronger than that of hydrocarbon compounds.
Description
Technical field
The present invention its relate to material detection technique field, be specifically related to a kind of for measuring flame photometric detector (FPD) that is phosphorous, sulfocompound.
Background technology
Gas chromatography detector is the device for detecting each separation component and concentration change thereof in carrier gas, its order
Be component and concentration change thereof be transformed in a different manner be easy to measure electric signal, the sorting technique of gas chromatography detector is a lot, usually integral form and derivative-type is divided into, integral detector shows a certain component concentration in time cumulative, when the material of different component is by detecting device, register is corresponding, and that obtain is a series of step figure.Differential detector shows a certain physical quantity over time, the chromatogram of gained is made up of the peak of a series of similar Gauss normal distribution shape, each peak corresponds to different components, area included by each peak is proportional to the content of this component, due to differential detector have highly sensitive, can trace components be measured, and the honeybee area of each component can be obtained and component retains data accordingly simultaneously, therefore adopted scope is comparatively extensive.
Summary of the invention
The object of this invention is to provide that a kind of it is for measuring phosphorous, sulfocompound for measuring flame photometric detector (FPD) that is phosphorous, sulfocompound, the signal that these compounds produce at flame is almost higher 10000 times than hydrocarbon.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises hydrogen flame part and luminosity part, and hydrogen flame part comprises flame-thrower nozzle, shading groove, lighter, and luminosity part comprises quartz window, optical filter and photomultiplier.
Principle of work: the compound of sulfur-bearing or phosphorus is carried by carrier gas, enter nozzle by detecting device bottom after first mixing with air (or pure oxygen), around nozzle, have four apertures, supply excessive combustion gas hydrogen, light the rich hydrogen flame that rear generation light is stable, the light trap that shading groove above nozzle can be used for flame itself and hydrocarbons to send goes, flame can be made so more stable, reduce noise, the characteristic light that the burning of sulphur, phosphorus produces is by quartz window, optical filter, then electric signal is converted to through photomultiplier, by registering instrument record chromatographic peak.
When the organic compound of sulfur-bearing or phosphorus burns in rich hydrogen flame, sulphur, phosphorus are excited and launch the spectrum of characteristic wavelength, and sulphur sends the blue-violet light of feature; Phosphorus then sends green light, filters, then carry out opto-electronic conversion by photomultiplier through optical filter, and the photocurrent of generation records corresponding chromatogram by register system after amplifier amplifies.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of for measuring flame photometric detector (FPD) that is phosphorous, sulfocompound, it is characterized in that comprising hydrogen flame part and luminosity part, hydrogen flame part comprises flame-thrower nozzle 1, shading groove 2, lighter 3, and luminosity part comprises quartz window 4, optical filter 5 and photomultiplier 6.
Claims (1)
1., for measuring a flame photometric detector (FPD) that is phosphorous, sulfocompound, it is characterized in that comprising hydrogen flame part and luminosity part, hydrogen flame part comprises flame-thrower nozzle, shading groove, lighter, and luminosity part comprises quartz window, optical filter and photomultiplier.
