In atomic absorption spectrography (AAS), use while having flame atomization, atomizer is the vitals of atomic absorption spectrophotometer (AAS), kapillary is again the vitals of atomizer, is placed in the middle of atomizer, external pipette, pipette is PE pipe mostly.In the time inhaling sample analysis, in the annular gap of kapillary outer wall and jet hole formation, because high pressure carrier gas is passed through at a high speed, form negative pressuren zone, thereby test solution, along capillary suction, and is dispersed into gasoloid (being droplet) by high velocity air, and the droplet of ejection touches and on impact bead, is further dispersed into mist, test solution after atomization enters premixing cavity fully to be mixed indoor with combustion gas, and the flame zone that then enters burner carries out a series of analytical test processes such as combustion ion.Very high in combustion process Flame temperature, be generally between 2000K-4000K, therefore, very high in combustion zone temperature, each parts are all high temperature resistant, so protective device is selected resistant to elevated temperatures polytetrafluoro.
What kapillary contacted in imbibition process is chemical reagent, and what therefore kapillary adopted is the platinum material of good stability, involves great expense, and in existing atomic absorption spectrophotometer (AAS), many equipment pipette are fixing not firm, and scope of activities is relatively large; In use, often there will be due to frequent operation imbibition process, pipette is fixed not firm can arbitrarily swing and is caused the in use stressed bending repeatedly of platinum kapillary, even fractures impaired.
Summary of the invention
Technical problem to be solved in the utility model is the problem for above-mentioned existence, and a kind of atomic absorption spectrophotometer (AAS) atomizer with kapillary protective device is provided, and can make pipette fixation, avoids the kapillary of atomizer main body to cause damage.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of atomic absorption spectrophotometer (AAS) atomizer with kapillary protective device; it is characterized in that; comprise atomizer main body, kapillary and pipette; kapillary passes from the center of atomizer main body; pipette one end and kapillary one end are connected; it is characterized in that; also comprise kapillary protective device; one side end face of described kapillary protective device has circumferential groove vertically, and atomizer main body top is fixedly installed in circumferential groove.
Press such scheme, described kapillary protective device has axis through-hole, described circumferential groove and axis through-hole central alignment, and the other end of pipette passes from axis through-hole.
Press such scheme, described kapillary protective device is made up of main protection body and semicylinder, and main protection body is right cylinder, is connected by bolt with semicylinder; Main protection body has axis through-hole, and main protection body one side end face has circumferential groove vertically; Main protection body opposite side outer circumference surface has right-angle notch, the footpath line parallel of the center line of the vertical plane of breach and main protection body, the dead in line of the center line of the surface level of breach and main protection body, semicylinder and breach phase configuration.
Press such scheme, a side outer circumference surface of described main protection body is provided with fixed pin.
Press such scheme, described bolt is hold-down bolt, the below pocketed springs of hold-down bolt.
Press such scheme, described hold-down bolt is symmetrical set on semicylinder.
Press such scheme, described described main protection body is polytetrafluoro material.
The beneficial effects of the utility model are: 1, atomizer main body top is fixedly installed in the circumferential groove of main protection body, by regulating the spacing between semicylinder and main protection body, be fixed pipette, avoid in use stressed bending repeatedly of kapillary; 2, simple in structure, reasonable in design, effectively protective hair tubule is injury-free.
