Abstract
The utility model discloses a needle tube dosing device which consists of a needle tube fixing cutting ferrule and a dosing rod, wherein, the middle of the needle tube fixing cutting ferrule is provided with a needle tube fixing hole, the needle tube fixing cutting ferrule on one side of the needle tube fixing hole is sleeved with a cutting ferrule opening, a dosing rod hole is arranged beside the needle tube fixing hole, one end of the dosing rod is provided with a fine thread, the other end is bent 90 DEG to be taken as a locating stop lever. During the use, the needle tube fixing cutting ferrule is lifted at the cutting ferrule opening, a glass injector is inserted into the needle tube fixing hole to be locked, a small bolt is used to firmly lock the glass injector in the needle tube fixing cutting ferrule, the dosing rod is screwed into the dosing rod hole on the needle tube fixing cutting ferrule, the dosing rod is adjusted, then the sampling is made; when the tail end of an injector core of the glass injector touches the locating stop lever on the dosing rod, the sampling is stopped, so the volumes taken by two samplings are completely same. The utility model has a simple structure, can conveniently realize the sing-hand operation, has high work efficiency, improves the consistency of sample injection volumes of the standard sample and the sample, and reduces analytical errors.
Description
One, technical field
The utility model relates to a kind of needle tubing proportioning device that is applied to gas chromatographic analysis external standard method sampling usefulness.
Two, background technology
When carrying out gas chromatographic analysis, make standard sample, compare with the response signal of component to be measured in standard sample and the sample and carry out quantitative methods and be called external standard method with the pure product of component to be measured.External standard method requires identical condition of work, so standard sample and sample are answered equal volume.At present, all the volume that adopts artificial visually examine's method affirmation sample introduction during hand sampling, all there is error in this method because of operator's difference, and just error is either large or small, but to analyzing certain influence is arranged all.
Three, summary of the invention
The technical problems to be solved in the utility model is: design a kind of needle tubing proportioning device, can significantly improve the sampling volume consistance of standard sample and sample, the personnel's that are not put to the test fully influence.
The technical scheme that solution the utility model technical matters is adopted is: fixedly cutting ferrule, quantitative bar are formed the needle tubing proportioning device by needle tubing, fixedly in the middle of the cutting ferrule needle tubing fixed orifice is arranged at needle tubing, needle tubing in needle tubing fixed orifice one side fixedly has a cutting ferrule opening on the cutting ferrule, establish a quantitative bar hole on needle tubing fixed orifice next door, quantitatively bar one end has fine thread, and crooked 90 degree of the other end are made the location pin.
In order to be applicable to the syringe that clamps different-diameter, a side corresponding with the cutting ferrule opening established an elastic dilatation hole on the needle tubing fixed orifice.
For syringe being fastened on needle tubing fixedly in the cutting ferrule, fixedly cut out a plane parallel on the cutting ferrule at cutting ferrule opening one side, needle tubing with the cutting ferrule opening, bore an aperture and pass the cutting ferrule opening perpendicular to the cutting ferrule opening in the plane, by a stove bolt by aperture with cutting ferrule opening needle tubing up and down fixedly cutting ferrule be connected and fixed.
The beneficial effects of the utility model are: simple in structure, easy to use, can realize one-handed performance, high efficiency very easily; Improved the sampling volume consistance of standard sample and sample, reduced analytical error, quantitatively volume is easy to adjust, and dismounting is safeguarded also very simple.
Four, description of drawings
Five, embodiment
Embodiment of the present utility model as shown in Figure 1, fixedly open a needle tubing fixed orifice 6 (as shown in Figure 2) in the middle of the cutting ferrule 1 at the needle tubing that nylon material is made, needle tubing fixed orifice 6 one sides have a cutting ferrule opening 9 with needle tubing fixedly cutting ferrule 1 separately establish an elastic dilatation hole 7 in a side of cutting ferrule opening 9 correspondences; Quantitatively bar hole 8 is located at needle tubing fixed orifice 6 belows, and quantitatively bar 2 one ends have fine thread, and crooked 90 degree of the other end are made the location pin; Fixedly cut out a plane 10 parallel on the cutting ferrule 1 at cutting ferrule opening 9 one sides, needle tubing with cutting ferrule opening 9, vertical cutting ferrule opening 9 bores apertures and passes cutting ferrule opening 9 on plane 10, by a stove bolt 5 by aperture with the needle tubing of cutting ferrule opening about in the of 9 fixedly cutting ferrule 1 couple together.The utility model can 50ml and two kinds of specifications of 100ml general, enlarged usable range.
Using method of the present utility model is: from cutting ferrule opening 9 with needle tubing fixedly cutting ferrule 1 raise, glass syringe 3 is put into needle tubing fixed orifice 6 to be blocked, with stove bolt 5 glass syringe 3 is clamped on needle tubing fixedly in the cutting ferrule 1, quantitative bar 2 is screwed in needle tubings fixedly in the quantitative bar hole 8 on the cutting ferrule 1, the sample of getting as required how much, regulate the position of location pin on the quantitative bar 2, get standard sample then, when piston 4 ends of glass syringe 3 contacted location pin on the quantitative bar 2, sampling stopped.The sample thief that uses the same method again is so the volume of being got for twice is duplicate.
