Accompanying drawing explanation
Below in conjunction with accompanying drawing, further illustrate the present invention.
Fig. 1 is light path principle figure of the present invention.
Fig. 2 is vertical view of the present invention.
Fig. 3 is structural representation of the present invention.
Embodiment
As Fig. 2, shown in 3, a kind of White pond formula flame atomizer, include three with the concave mirror M1 of focal length, M2, M3, concave mirror M1 is identical with M2 size and be fixed on side by side one end of full titanium optical table 1, concave mirror M3 is fixed on the other end of full titanium optical table 1, the concave surface of concave mirror M1 and M2 is relative with the concave surface of concave mirror M3, described concave mirror M1, distance between M2 and concave mirror M3 is the radius-of-curvature of the concave mirror of this kind of focal length, be positioned at concave mirror M1, on full titanium optical table 1 between M2 and concave mirror M3, be fixed with full titanium burning plate 2, full titanium optical table 1 is welded on full titanium burning seat 3, guarantee that in combustion process, gas is not revealed.
Concave mirror M1, M2, M3 are that draw-in groove and the glue by opening on full titanium optical table 1 is fixed on full titanium optical table, first on full titanium optical table 1, open draw-in groove, make concave mirror M1, M2, M3 just in time snap in respectively in draw-in groove, and in draw-in groove, coat sticky eyeglass glue special, to guarantee the firm of eyeglass.
Full titanium optical table 1 and full titanium burning plate 2 are fixing by stainless steel holding screw 4, full titanium burning plate 2 and full titanium optical table 1 contact position are coated with one deck thermostable heat-isolating coating, can play sealing function, the temperatures involved concave mirror producing in the time of flame combustion can being stoped again.
It is 12 times that this flame atomizer reflects light path by concave mirror.
Full titanium burning plate 2 comprises 12 flame seams, and the width of every flame seam is 0.5mm; Distance between flame seam is 0.6mm.
Specific works flow process is referring to Fig. 1 and Fig. 3, incident light after monochromator light splitting, by a plane mirror, reflex on concave mirror M1, concave mirror M1 is identical with M2 size, and the distance between concave mirror M1, M2 and concave mirror M3 is the radius-of-curvature of the concave mirror of this kind of focal length, like this, it is upper that all light that send arbitrfary point from concave mirror M1 all can be gathered M2 by M3, and all light that send from concave mirror M2 also can be gathered the upper initial point of M1 by M3.The light that light source sends incides M1, then reflexes to M3, then reflexes to M2 by M3, gets back to M3, then to M1, and to the last reflected light once penetrates from M3, moves in circles, and light is recycled like this in the process moving in circles.
Be arranged on the full titanium burning plate on full titanium optical table, just in time between three concave mirror M1, M2, M3, the light moving in circles by three concave mirror reflections, flame seam through 12 burnings simultaneously, sample solution produces ground state atom in burned flame, absorb the light of concave mirror reflection, light is by multiple reflections, just repeatedly absorbed, be equivalent to increase absorption light path, compare with traditional single seam flame atomizer, improved the utilization factor of light, dwindled the volume of atomizer.For realizing miniaturization, portable Atomic Absorption Spectrometer is laid a good foundation.
