Description
Technical field
The present invention relates to the packoff in the analytical test field, say further, relate to a kind of be used to sealing device capillaceous.
Background technology
Often use the kapillaries such as quartz capillary or glass capillary in the analysis such as Capillary Electrophoresis, gas chromatograph instrument, during experiment finishes, usually kapillary is taken off from instrument, entered kapillary for avoiding water in air steam, oxygen, dust etc., the kapillary two ends need be sealed.Now the general way in laboratory is that a fritter block rubber (as the gas chromatographic sample introduction pad etc.) is inserted at kapillary two ends, and then there are a lot of defectives in this method, and for example the broken end of block rubber easily enters kapillary, stops up; In addition, if misoperation is easy to cracked as the two ends of quartz capillary or glass capillary.This just need to block kapillary two ends cracked or that stop up, the kapillary that perhaps more renews.Yet, as often expensive in quartz capillary, and again change kapillary and waste time and energy.Thereby, substitute in the urgent need to a kind of new apparatus and method the block rubber that tradition is used.
The utility model content
The utility model has proposed a kind of be used to sealing device capillaceous for the problem that exists in existing method.Device is simple, low price, easy to operate, reusable, good airproof performance, can prevent preferably that water in air steam, oxygen, dust etc. from entering kapillary.
Of the present utility modelly a kind ofly comprise gas-tight silo be used to sealing device capillaceous, joint and separator tube 3; Described gas-tight silo hollow and comprise at least a port; Described joint closely is arranged on described gas-tight silo passage port; Described separator tube 3 is arranged in joint; The internal diameter of described separator tube 3 is greater than the external diameter of kapillary 4; Be inserted in described separator tube 3 in described kapillary 4.
In concrete enforcement, described gas-tight silo is tapered cup nut or two-way pipe fitting.
The port diameter of the external diameter of described joint and described tapered cup nut or two-way pipe fitting is adaptive, and described joint is that hand is twisted joint 2.
Preferably, described hand is twisted the inner port of joint 2 and is alignd with the inner port of separator tube 3, i.e. the end that tapered cup nut or two-way pipe fitting are advanced in stubborn joint 2 spies of described hand aligns with the inner port of described separator tube 3.
Be arranged on the inner port that kapillary 4 inner port in described separator tube 3 are not stretched out described separator tube 3.
The utility model wherein a kind of embodiment is, described gas-tight silo is two-way pipe fitting 1, and described two-way pipe fitting 1 comprises two ports, is provided with two hands and twists joint 2 in described two ports; The interior insertion in the stubborn joint 2 of described hand of two separator tubes, 3 difference that comprises 1 capillary 4 or two capillaries 4.A described capillary 4 is coil pipe; Described two capillaries 4 are straight tube.
Described joint can be the peek joint.
Described kapillary 4 is selected from a kind of in glass capillary, quartz capillary, stainless steel capillary.
Described separator tube 3 can be this area common used materials such as peek pipe, and is impaired under pressure for the protection of kapillary;
Described two-way inside pipe fitting arranges a sealing, and described sealing is twisted joint 2 separately with the described hand at two ends.
A kind of using method be used to sealing device capillaceous of the present utility model is:
Select the separator tube 3 of adaptive suitable dimension according to the kapillary external diameter size of need protection, described kapillary 4 is inserted in separator tube 3, make kapillary 4 ends just not stretch out separator tube 3.
Two separator tubes 3 that are inserted with kapillary 4 are inserted respectively in the stubborn joint 2 of two hands, more described two hands are twisted joint 2 insert respectively in two ports of described two-way 1.
Manually tighten described hand and twist joint 2, separator tube 3 is shunk, thereby compress kapillary 4 ends, thus with kapillary 4 closed at both ends on two-way, kapillary 4 inner chambers are isolated from the outside, avoid dust in air, oxygen, water vapor etc. to enter kapillary 4.
The two-way pipe fitting that uses in the utility model can be this area two-way pipe fitting commonly used, also the two-way pipe fitting slightly can be made improvements, the cavity of two-way pipe fitting is sealed in the middle, thereby the port at two-way pipe fitting two ends is not communicated, form two and independently connect port; Two connect port all to carry tieing adaptive with hand.In concrete the use, kapillary 4 can be inserted the peek pipe, then the peek pipe is inserted the peek joint again; after peek joint insertion two-way connection port is tightened, just sealed, this moment, kapillary 4 was very tightly stubborn; pull out to get off, thereby play good protection and sealing process.
Device of the present utility model can be used for the sealing capillaceous used in the analysis instruments such as gas chromatograph, Capillary Electrophoresis, avoid the fracture of capillary end in sealing as the kapillary process of the frangible materials such as quartz or glass, thereby effectively extend serviceable life capillaceous.Apparatus structure of the present utility model is simple, easy to operate, low price, reusable, can prevent preferably that water in air steam, oxygen, dust etc. from entering kapillary, is worthy of popularization.
