Abstract
A capillary chromatographic column storing sleeve relates to a capillary column storing sleeve. The aim of the invention is to settle the problems of no easy storing, gradually shortening of the capillary length and inferior separating effect existing in the prior capillary chromatographic column. The storing sleeve is composed of a glass sleeve, a small-diameter pipe, a silicon rubber plug, a latex pipe and a clamper. The two ends of the glass sleeve are respectively provided with a rubber plug socket matched with the silicon rubber plug. The axis in the glass sleeve between two rubber plug sockets is provided with a small-diameter pipe with the diameter larger than the outer diameter of the capillary chromatographic column for 0.08mm-0.12mm. The glass sleeve is provided with a vent pipe communicated with the small-diameter pipe. The outer end of the vent pipe is communicated with the latex pipe. The clamper is provided on the latex pipe. The silicon rubber plug is a cone and is divided into two symmetric halves along the axis. The axis of each half of the silicon rubber plug is processed with a semicircular groove with an outer diameter equal with the outer diameter of the capillary chromatographic column. The capillary chromatographic column storing sleeve of the invention is used for storing the capillary chromatographic column.
Description
Technical field
The present invention relates to a kind of chromatographic column storing sleeve.
Background technology
Capillary chromatographic column has been widely used in gas chromatographic analysis, and a common gas chromatography will be equipped with the chromatographic column of several opposed polarities, and the characteristic according to component to be measured during analysis is changed chromatographic column.Because the capillary column inside coating is easily by airborne dioxygen oxidation, impurity such as grieshoch also enter in the post from the chromatographic column two ends easily, descend or appearance " ghost peak " thereby the chromatographic column post is imitated, and therefore, the two ends of the chromatographic column of unloading down need seal preservation.
At present, capillary chromatography column sealing preservation way commonly used is the chromatographic column two ends to be inserted in the silica gel head that discarded injection port dottle pin or chromatographic column carry preserve, this method effectively blocks air and dust enters in the chromatographic column, but, when utilizing this chromatographic column, the post two ends need be clipped about 1cm next time, enter into the chromatographic column influence with post analysis to avoid the minor amount of silicon rubber scraps.The chromatographic column of same quality is long more, and separating effect is good more.Therefore, after replacing chromatographic column repeatedly, the chromatographic column total length can shorten gradually, and separating effect also can variation.In addition, during the cutting chromatographic column, require tangent plane level and smooth, improper or operating personnel's lack of skill as instrument will repeatedly just can be finished usually, and the time of so both having wasted also makes the length of chromatographic column further shorten.When the distance that enters chromatographic column when the silica gel chip surpassed 1cm, this method can not effectively be removed the silica gel chip.
Summary of the invention
The objective of the invention is chromatogram length is shortened gradually, cause the problem of inferior separating effect, proposed a kind of capillary chromatographic column storing sleeve in order to solve existing capillary chromatography column sealing preservation way.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described preservation sleeve pipe is by glass bushing, small-bore pipeline, two sillicon rubber blockings, emulsion tube and clip are formed, the two ends of described glass bushing have the plug socket that is complementary with sillicon rubber blocking respectively, axis place in the glass bushing between described two plug sockets is provided with the small-bore pipeline of diameter than the big 0.08mm～0.12mm of capillary chromatographic column external diameter, described glass bushing is provided with the gas outlet that is connected with small-bore pipeline, the outer end of described gas outlet is communicated with emulsion tube, on the described emulsion tube clip is housed, described sillicon rubber blocking be Rotary-table and along axis be split up into the symmetry two lobes, the axis place of every lobe sillicon rubber blocking 4 is processed with the semicircle groove that equates with the capillary chromatographic column external diameter.
The present invention has following beneficial effect: the groove among the present invention between two lobe silicon rubber is identical with the chromatographic column external diameter, has good air-tightness behind the jam-pack; Space between the sillicon rubber blocking of jam-pack and plug mouth is minimum, the small-bore pipeline diameter of glass bushing is only than the big 0.1mm of chromatographic column external diameter, this air content that makes seal cavity seldom, can effectively prevent chromatographic column oxidation by air and enter impurity in the preservation process, and do not need chromatogram column cap excised when using next time, simple to operate, preparation cost is also lower.
Description of drawings
Fig. 1 is that one-piece construction master of the present invention looks synoptic diagram, and Fig. 2 is that the master of sillicon rubber blocking 4 looks cut-open view.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, described preservation sleeve pipe is by glass bushing 1, small-bore pipeline 3, two sillicon rubber blockings 4, emulsion tube 6 and clip 7 are formed, the two ends of described glass bushing 1 have the plug socket 2 that is complementary with sillicon rubber blocking 4 respectively, axis place in the glass bushing 1 between described two plug sockets 2 is provided with the small-bore pipeline 3 of diameter than the big 0.08mm～0.12mm of capillary chromatographic column external diameter, described glass bushing 1 is provided with the gas outlet 8 that is connected with small-bore pipeline 3, the outer end of described gas outlet 8 is communicated with emulsion tube 6, on the described emulsion tube 6 clip 7 is housed, described sillicon rubber blocking 4 is split up into two symmetrical lobes for Rotary-table and along axis, and the axis place of every lobe sillicon rubber blocking 4 is processed with the semicircle groove 5 that equates with the capillary chromatographic column external diameter.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, gas outlet 8 internal diameters are 0.1mm, and described gas outlet 8 vertical glass bushings 1 lead to outside the pipe, and the advantage of this syndeton is for can discharge excess air.Other compositions and annexation are identical with embodiment one.
Embodiment three: present embodiment is described in conjunction with Fig. 1, angle β between the side of described plug socket 2 and the angle α between the axis and sillicon rubber blocking 4 sides and the axis should satisfy 3 °＞alpha-beta＞1 °, and the advantage of this syndeton is for having good air-tightness.Other compositions and annexation are identical with embodiment one.
The course of work: during work, end with capillary chromatographic column is clipped between the semicircle groove 5 of two lobe sillicon rubber blockings 4 earlier, and lean out the minor diameter round table surface radius end 2～3cm of sillicon rubber blocking 4, the other end with capillary chromatographic column is inserted in the small-bore pipeline 3 of glass bushing 1 then, again sillicon rubber blocking 4 is inserted plug socket 2, the minor diameter round table surface of sillicon rubber blocking 4 is overlapped with the minor diameter round table surface of plug socket 2, the other end with capillary chromatographic column also adopts identical operations to insert the end in addition of glass bushing 1 again, with clip 7 gas outlet 8 is sealed at last.
