Abstract
The utility model provides a liquid is syringe for sample collection, including the capillary hose capillary hose end's skin overlaps respectively from inside to outside and is equipped with hard tube, carbon fiber tube and the long hot pipe of moulding, hard tube and carbon fiber tube mould tub parcel through long heat and fix the skin at the capillary hose. The utility model has the beneficial effect of simple structure, preparation low cost, intensity improves very greatly, has certain bending property, and difficult rupture endures acid and alkaline corrosion completely.
Description
Technical field
The utility model relates to a kind of fluid sample sampler, particularly relates to a kind of liquid sample collecting sample introduction needle.
Background technology
Atomic fluorescence spectrophotometer is a kind of chemical analysis instrument for measuring element trace level content in sample.Its principle of work utilizes chemical method to make tested element generation chemical reaction generate hydride, by atomizer outlet through lighting formation flame, light source activation is utilized to contain the flame of tested element, tested element produces atomic fluorescence after obtaining energy jump, by measuring the intensity of atomic fluorescence, calculate tested constituent content by analysis.Need in instrument work to connect automatic sampler, draw liquid sample by sample introduction needle, carry out analysis and detect.The sample introduction needle adopted in prior art is the end of tubular needle that quartz glass makes internal diameter 1mm external diameter 3mm, length more than 200 millimeter, although the acid and alkali corrosion of sample well can be tolerated, but still there is following drawback: 1. frangibility, because of the tubular structure that sample introduction needle is elongated, in use and in instrument maintenance servicing operations, be easy to cause sample introduction needle to fracture, and then affect the continuity of testing; 2. manufacture difficulty is large, and cost is high.Because of the singularity of its material and the elongated feature of size, sample introduction needle inwall poor quality controls, and cost is very high.
Utility model content
The purpose of this utility model is to provide a kind of liquid sample collecting sample introduction needle, and its structure is simple, and cost of manufacture is cheap, and intensity improves very large, has certain bending property, the not complete tolerance acid-base corrosion of frangibility.
The technical solution of the utility model is: a kind of liquid sample collecting sample introduction needle, comprise capillary soft tube, be respectively installed with hard tube, carbon fiber pipe and long thermoplastic tube from inside to outside at the skin of described capillary soft tube one end, described hard tube and carbon fiber pipe are wrapped on the skin of capillary soft tube by long thermoplastic tube.
Further, the material of described capillary soft tube is teflon.
Further, the material of described hard tube is teflon.
Further, reinforced the connection by short thermoplastic tube at the afterbody of described long thermoplastic tube.
Further, the angle of inclination of described sample introduction needle liquid feeding end is 120 degree of-180 degree.
Further, the angle of inclination of described sample introduction needle liquid feeding end is 150 degree.
The advantage that the utility model has and good effect are: the sample introduction needle that the utility model provides a kind of brand-new material to make, the capillary soft tube overcoat carbon fiber pipe adopting teflon material to make supports, the hard tube that the teflon material being aided with thick specification between capillary soft tube and carbon fiber pipe is made, the long thermoplastic tube of external overall wraps, its intensity improves very large, there is certain bending property, the not complete tolerance acid-base corrosion of frangibility.

Fig. 1 is structural representation of the present utility model.
In figure:
1, carbon fiber pipe 2, hard tube 3, capillary soft tube
4, long thermoplastic tube 5, short thermoplastic tube
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Fig. 1 the utility model structural representation, the utility model provides a kind of liquid sample collecting sample introduction needle, comprise capillary soft tube 3, be respectively installed with hard tube 2, carbon fiber pipe 1 and long thermoplastic tube 4 from inside to outside at the skin of described capillary soft tube 3 one end, described hard tube 2 and carbon fiber pipe 1 are wrapped on the skin of capillary soft tube 3 by long thermoplastic tube 4.
The material of described capillary soft tube 3 is teflon.The material of described hard tube 2 is teflon.Reinforced the connection by short thermoplastic tube 5 at the afterbody of described long thermoplastic tube 4.
The angle of inclination of described sample introduction needle liquid feeding end is 120 degree of-180 degree.The angle of inclination of described sample introduction needle liquid feeding end is 150 degree.
The course of work of this example: the sample introduction needle that the utility model provides a kind of brand-new material to make, the capillary soft tube 3 overcoat carbon fiber pipe 1 adopting teflon material to make supports, the hard tube 2 that the teflon material being aided with thick specification between capillary soft tube 3 and carbon fiber pipe 1 is made, the long thermoplastic tube 4 of external overall wraps, its intensity improves very large, reinforced the connection by short thermoplastic tube 5 at the afterbody of described long thermoplastic tube 4, there is certain bending property, the not complete tolerance acid-base corrosion of frangibility, sample introduction needle liquid feeding end angle of inclination be 150, facilitate imbitition sample.The complete tolerance acid-base corrosion of sample introduction needle, and its intensity improves very large, has certain bending property, not frangibility.Cost significantly reduces, and by original 300 yuan/, is reduced to less than 30 yuan/props up.More because its design feature, the capillary soft tube pipette samples that inner core is made by a through teflon, the quartz glass tube sample introduction needle comparatively connects the mode of capillary soft tube pipette samples again, and fluid sample circulation is more unobstructed.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
