Abstract
The utility model relates to the technical field of liquid-phase chromatogram mass spectrum combined analysis, which is composed of an L-shaped dispersed air spraying pipe, a capillary and a sealing ring. The pipe opening of an inner casing pipe in the L-shaped dispersed air spraying pipe is positioned between an air entering opening and a nozzle. The capillary closely adheres to and passes through the inner wall of the inner casing pipe, and the capillary can directly be communicated towards any position of the nozzle. The outer end of the inner casing pipe is provided with a sealing plug, and the center of the sealing plug is provided with a hole through which the capillary can pass. The utility model can adjust the relative positions of the outlet of the capillary and the nozzle of an atomizer in order to change the injection state of sample flowing phase solution to reach optimal purpose of atomization. The utility model advances the sensitivity of measurement, and the atomizer is easily cleaned.
Description
The utility model relates to a kind of particle beams atomizer, belongs to the liquid chromatograph mass spectrography technical field of analytical instruments.
Liquid chromatograph mass spectrography is extremely to pay attention to the analytical technology that develops rapidly in recent years, partical beam is one of technique device of realizing this coupling, atomizer is one of core component of partical beam, and its design considerations is the materialization property and the liquid-phase chromatographic analysis technology characteristics different separately with analytical technique of mass spectrum of viscosity, volatile grade and the sample material of mobile phase solvent.
The kapillary of defeated mobile phase solvent only feeds 1/3rd long places of atomizer inner sleeve in the prior art atomizer, and sleeve pipe is through to atomizer spout place; The kapillary degree of depth is nonadjustable like this, and very easily will break up than thin inner sleeve during logical kapillary, easily sticks together between kapillary and the inner sleeve; Slit easy cleaning not between sleeve pipe and the atomizer wall, different solvents usually needs to change different atomizers.
The purpose of this utility model is to remedy the deficiency of prior art, and a kind of adjustable particle beams atomizer is provided.
The utility model is made up of L shaped dispersed gas jet pipe, kapillary and the sealing-plug of band inner sleeve.As shown in Figure 1.The inner sleeve mouth of pipe is good in the middle of the two between air intake opening and spout; The kapillary external diameter is consistent with inner sleeve and spout internal diameter, and kapillary can be close to the inner sleeve inwall just and therefrom pass, and the kapillary mouth of pipe can and be close to the spout inwall through to the spout place; The spout end closes up gradually, and spout is apart from beginning closing in place apart from 5-15mm.The porose internal diameter in sealing-plug center of inner sleeve outer end is consistent with the kapillary external diameter, and kapillary can therefrom be passed just; For well, sealing-plug not only plays sealing function to logical kapillary place to sealing-plug, can also help to regulate simultaneously fixedly nozzle position of the kapillary degree of depth with silastic material.Kapillary is good with the elastic quartz material, and L shaped gas dispersion pipe (comprising inner sleeve) can be quartz glass, hard glass or metal material.Relevant size can be with reference to prior art, and the inner sleeve tube wall is thickeied a little.
Analyzed sample is carried together by mobile phase solvent after liquid chromatography is separated and enters atomizer by kapillary, arrive nozzle exit area, disperse gas then to enter atomizer through L shaped jet pipe, the slit that forms through between kapillary outer wall and spout inwall at the spout place sprays at a high speed, sample flow phase solvent spray band is formed tiny atomized drop, and kapillary can be regulated by adjusting sealing-plug in the position at spout place.Different molecular weight and materialization property at mobile phase solvent and sample compound, regulate the relative position of capillary outlet end and atomizer spout, change spray regime to reach best atomizing purpose, make that atomizing is more complete, drop is more even tiny, improve detection sensitivity.
The utility model both can have been realized the free adjustment of spray pattern, can keep high vacuum not suffer a loss again, and avoided in the past product easily to cause kapillary adhesion, fragile, the deficiency of easy cleaning not.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model diagrammatic cross-section, wherein, and 1. spout, 2. capillary exit, 3. kapillary, 4.L shape dispersed gas jet pipe, 5. inner sleeve, 6. gas inlet port, 7. sealing-plug.
Fig. 2 is a particle beams liquid chromatograph mass spectrography interface synoptic diagram, it is application signal of the present utility model, wherein, moving phase solution atomizes through atomizer A, drop enters desolventizing chamber B, and under temperature and one-level pump C, two stage pump D effect, solvent evaporation is taken away in the drop, sample solute formation particle enters mass ion source E and is ionized, thereby obtains to analyze.This shows that atomizer atomizing effect quality is crucial for sensitivity and the accuracy analyzed.
Embodiment. structure is as shown in Figure 1.L shaped pipe range 50mm, external diameter 6mm, internal diameter 4mm, wall thickness 1mm; Spout external diameter 1.5mm, internal diameter 0.3mm, wall thickness 0.6mm, spout is apart from beginning closing in place apart from 10mm; The long 20mm of inner sleeve, external diameter 1.5mm, internal diameter 0.3mm; Elastic quartz capillary tube external diameter 0.3mm, internal diameter 0.1mm.Sealing-plug is a silastic material, and its internal diameter is identical with the kapillary external diameter, and external diameter is identical with inner sleeve outer end recess internal diameter.
