Abstract
The utility model discloses an effluent discharge device improving stability of an ICP spectrometer sample introduction system, which comprises a peristaltic pump, a flexible tube, a water-sealed bottle and a connecting pipe which are sequentially connected. The connecting pipe is connected with an atomizing chamber of the ICP spectrometer sample introduction system. The atomizing chamber of the effluent discharge device leads the discharge speed of effluent to match with the effluent generating speed of the atomizing chamber by adjusting steering and rotation speed of the peristaltic pump, so that the height of effluent level in the water-sealed bottle maintains unchanged, pulse effluent discharge can be avoided, aerosol flow fluctuation caused by the impulse effluent discharge is effectively eliminated, and the stability of the ICP spectrometer sample introduction system is improved.
Description
Technical field
The utility model relates to a kind of ICP spectrometer, particularly a kind of waste liquid discharger that improves ICP spectrometer sampling system stability.
Background technology
The ICP spectrometer is a kind of Atomic Emission Spectrometer AES device of precision, and chief component comprises several parts such as inductively coupled plasma generator (being the ICP light source), sampling system, beam splitting system, photo-translating system, signal Processing.Wherein, the inductively coupled plasma generator produces plasma torch, and the high temperature of torch can excite sample atoms of elements to be analyzed, thereby produces the signature analysis line of this element; Sampling system is used for sample solution to be measured is formed gasoloid, and this gasoloid is sent into deexcitation in the plasma torch; The wavelength separated of the signature analysis line that beam splitting system is then sent plasma torch comes and qualitative its wavelength; Photo-translating system then is converted to electric signal with the light intensity signal of analytical line; Signal Processing comprises that amplification, filtering, the AD of photoelectric conversion signal change, calculate or the like.
A very important system in the sampling system formula ICP spectrometer, the stability of sampling system and repeatability directly influence the stable and repeated of ICP spectrometer complete machine.The major function of sampling system is exactly that sample solution to be measured is formed the gasoloid that mixes all by atomizer and spray chamber, by spray chamber this gasoloid is imported the central passage of torch pipe then, excite, can in spray chamber, big droplet be collected the formation waste liquid simultaneously.In the common use, the waste liquid that forms in the spray chamber generally is discharged in the waste collection bottle by devices such as water-sealed drainage bottles.Traditional waste liquid dischargers such as water-sealed drainage bottle are work like this: have certain amount of fluid in water-sealed drainage bottle, to reach the purpose with spray chamber and outside air isolation.Along with waste liquid is little by little discharged, the liquid level in the water-sealed drainage bottle can slowly rise.When liquid level rose to the waste liquid escape hole of water-sealed drainage bottle upper end, excess liquid can flow out through the waste liquid escape hole, thereby made the interior liquid level of water-sealed drainage bottle remain at the following section part of waste liquid escape hole, had both guaranteed secluding air, can discharge unnecessary waste liquid at any time again.But in the use of reality, find, when the liquid level of waste liquid in the water-sealed drainage bottle surpasses the waste liquid escape hole of water-sealed drainage bottle upper end, because the capillary existence of waste liquid, the waste liquid that exceeds the escape hole part does not flow away along escape hole at once, but continuing accumulation, liquid level continues to rise, after liquid level rises to a certain degree, when the pressure differential that the liquid level difference forms can overcome surface tension, exceed this part waste liquid of escape hole and just all flow away quickly.Will produce the pulsation effect that waste liquid is discharged like this.This pulsation effect can directly influence the aerocolloidal flow velocity in spray chamber exit, and then directly influences the stability of gasoloid sample introduction, causes the poor stability of analysis result.
So developing a kind of novel waste liquid discharger has become the technical matters that needs to be resolved hurrily in this area.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of waste liquid discharger of new raising ICP spectrometer sampling system stability, this waste liquid discharger has redesigned the discharge mode of spray chamber waste liquid, not by the waste liquid escape hole effluent discharge on the water-sealed drainage bottle, and adopt initiatively effluent discharge of peristaltic pump.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of waste liquid discharger that improves ICP spectrometer sampling system stability, it comprises peristaltic pump, flexible pipe, water-sealed drainage bottle and the connecting pipe that connects successively.
Preferably, described water-sealed drainage bottle is provided with discard solution discharge port.
Such scheme has following beneficial effect: above-mentioned waste liquid discharger, by regulating turning to and rotating speed of peristaltic pump, make the efflux velocity of waste liquid and the speed that spray chamber generates waste liquid adapt, so that the waste liquid liquid level in the water-sealed drainage bottle remains unchanged, the phenomenon of pulsating discharge opeing can not take place, eliminate the phenomenon of the gasoloid flow velocity fluctuation that causes owing to the pulsation discharge opeing effectively, improved the stability of sampling system.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below elaborates with preferred embodiment of the present utility model and conjunction with figs..Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of waste liquid discharger that improves ICP spectrometer sampling system stability, it comprises peristaltic pump 1, connection flexible pipe 2, water-sealed drainage bottle 3 and the connecting pipe 5 that connects successively, connecting pipe 5 is connected with spray chamber 8, preferably, water-sealed drainage bottle 3 is provided with discard solution discharge port 4.
This waste liquid discharger is when work, testing sample enters spray chamber 8 by the inlet on the atomizer 96, the gasoloid that produces is discharged by the outlet on the spray chamber 8 10, by regulating turning to and rotating speed of peristaltic pump, make the efflux velocity of waste liquid and the speed that spray chamber generates waste liquid adapt, so that the waste liquid liquid level in the water-sealed drainage bottle remains unchanged, the phenomenon of pulsating discharge opeing can not take place.
More than the waste liquid discharger of a kind of ICP of raising spectrometer sampling system stability that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
