Abstract
An atomizing device which combines pneumatic atomization with ultrasonic atomization belongs to the field of chemical analysis instruments, in particular to an atomic optical spectrum analyzer, such as an atomic absorption spectrometer and a plasma emission spectrometer. The existing normal pneumatic atomization device has low atomization efficiency, and accordingly leads the atomic optical spectrum analyzer to have low sensitivity and high detection limit. However, the efficient atomizer replaces an impact bead of a pneumatic atomization device with an ultrasonic vibration device, combines two existing atomization manners, improves atomization efficiency, overcomes defects of each single atomization manner, and improves performances of the atomic optical spectrum analyzer.
Description
Technical field
The utility model belongs to atomic spectroscopic analysis field in the analytical chemistry, is applicable to the atomic spectroscopic analysis instrument, is a kind of sampling device.
Background technology
In the atomic spectroscopic analysis technology, fluid sample atomizing sample introduction is most convenient, the most stable, the most the most frequently used input mode.The raising of nebulization efficiency can obtain higher sensitivity and lower detection limit, so be the focus and the difficult point of research in recent years always.Atomizing type has two kinds at present, and a kind of is pneumatic nebulization, and a kind of is ultrasonic atomizatio.Pneumatic nebulization is simple in structure, and is with low cost, easy to operate, use very general, but nebulization efficiency is very low, has only 10%-15%.Ultrasonic atomizatio is a kind of new technique, and nebulization efficiency significantly improves, and has had commercial equipment to occur, but this atomizing type apparatus expensive, sample are in the spectral instrument exterior atomization, by introducing instrument than long pipe runs, complex structure, residual effect is obvious, operation inconvenience.
Summary of the invention
In order to improve the sensitivity of atomic spectroscopic analysis, obtain lower detection limit, improve the nebulization efficiency of sample, do not increase simultaneously instrument purchase cost and use cost, do not increase the complexity of instrument, make operating personnel time saving and energy saving.
The technical scheme that its technical problem that solves the utility model adopts is: general pneumatic nebulization device is provided with a glass impact bead in nozzle the place ahead of Venturi tube, when feeding driving gas, part liquid is in the atomizing of nozzle place, and another part hits impact bead when forming drop ejection greatly.Knock the drop of impact bead, a part atomizes because of bump, and the not atomizing of most of liquid forms big drop on impact bead, become waste liquid.The utility model changes static impact bead into ultrasonic vibration installation here.When big drop sprays from Venturi tube, hit on ultrasonic vibration installation, can be more than hitting on static glass marble atomizing.Simultaneously, still not atomizing condenses in the big drop on the ultrasonic vibration installation behind the bump, also can atomize because of ultrasonic vibration.Therefore nebulization efficiency is improved, and along with the atomizing and the blowing of driving gas of sample liquids are hit, the heat dissipation problem of ultrasonic vibration installation has also solved.
The utility model is with pneumatic nebulization and ultrasonic atomizatio combination, become a kind of new atomizer, the advantage of having gathered two kinds of atomizing types, the nebulization efficiency height, simple in structure, volume is small and exquisite, cheap, easy to operate, can be installed in the atomic spectroscopic analysis instrument internal, residual effect is very little, instrumental sensitivity is improved, and detection limit reduces.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1. sample introduction capillaries among the figure, 2. sleeve pipe, 3. luffing bar, 4. ultrasonic transducer, 5. support bar, 6. ultrasonic drive circuit, 7. auxiliary gas inlet, 8. waste liquid outlet, 9. atomizer housing, 10. burner.
The specific embodiment
Sample introduction capillary (1) and sleeve pipe (2) are formed Venturi tube commonly used among the figure, and driving gas feeds from sleeve pipe (2), drive the sample liquids in the sample introduction capillary (1), form spraying at the nozzle place.Drive ultrasonic transducer (4) by ultrasonic drive circuit (6) and form ultrasonic vibration, radiate from end face through luffing bar (3), the big drop that does not form mist of Venturi tube ejection impinges upon the end face of horn,amplitude transformer (3), atomizes under action of ultrasonic waves.Pneumatic and ultrasonic two kinds of produced simultaneously sample mists of effect, the gas that driving gas that is entered by sleeve pipe (2) and auxiliary gas inlet (7) enter is brought burner (10) together into, produces atom spectrum, measures.A small amount of do not have the sample of atomizing to go up the big drop of formation at luffing bar (3) or transducer (4), drops on atomizer housing (9) bottom, discharges from waste liquid outlet (8).
