Abstract
The utility model relates to a chromatographic column cover with a ventilating pipe. The chromatographic column cover comprises a cover body, the ventilating pipe, a liquid discharging pipe, a movable valve and a column body, wherein the chromatographic column cover is provided with a cylindrical column body, and the liquid discharging pipe with the movable valve is arranged at the lower part of the column body; a liquid storage chamber with the diameter which is greater than that of the column body is arranged above the column body; an opening with the diameter which is less than that of the column body is arranged at the upper part of the liquid storage chamber; the hollow cover body with a bent upper part is arranged at the opening in a matched manner; the cover body is arranged in a way that the diameter of the lower end of the cover body is matched with the diameter of the opening; and the front end of the cover body is provided with an opening, and the opening is fixedly provided with one through ventilating pipe which directly passes through the tail end of the cover body. The chromatographic column cover has the advantages of being simple in structure and strong in practical applicability and can be widely popularized and used.
Description
Technical field
The utility model relates to a kind of lid that is used to separate the chromatographic column of various mixtures, especially a kind of chromatographic column lid with breather pipe.
Background technology
Chromatography is to utilize the difference of different material physicochemical property and the technology set up.Tomographic system is all by two phase compositions: the one, and fixing phase, another is a flowing phase.When mixture to be separated passes through fixedly phase time with flowing phase; Because the physicochemical property of each component there are differences; The ability of (absorption, dissolving, combination etc.) of interacting mutually with two is different; Different in two distribution in mutually, and along with the moving forward of flowing phase, each component is constantly reallocated in mutually two.Collect respectively and flow out liquid, can obtain each contained in sample one-component, thereby reach the purpose that each component is separated.At present, existing chromatographic column is the glass column of a similar acid buret, and valve is arranged below, and the scalable liquid droping speed has sieve plate on valve top, blocks adsorption column.But do not have lid above the existing glass post mostly, make airborne dust be prone to get into glass tube, pollute flowing phase, and when needs improve the glass column pressure inside with the increase liquid droping speed, be difficult to realize the raising of pressure yet.
The utility model content
In order to solve the deficiency of prior art, the utility model provides a kind of chromatographic column lid with breather pipe.This cap structure is simple, practical.
The utility model solves the technical scheme that its technical problem adopted: the chromatographic column lid of band breather pipe comprises lid, breather pipe, drain pipe, live valve, cylinder; This chromatographic column lid has the cylinder of a tubular; The bottom of cylinder is the drain pipe of a band valve alive, and the cylinder top is the fluid reservoir of a diameter greater than cylinder, and the opening of a unlimited diameter less than cylinder arranged at fluid reservoir top; Mate the lid of the hollow that a top bending is installed with opening; The installation that is complementary of the diameter of lid lower end and opening diameter, the front end of lid has opening, and opening is installed with a penetrating breather pipe that straight-through lid is terminal.During use, this lid cooperates installation to get final product with the cylinder opening.
The utility model compared with prior art has the following advantages: the lid of top bending can prevent that dust in air from falling into the pollution that chromatographic column causes chromatographic column flowing phase; The terminal breather pipe of straight-through lid that the lid front opening is installed can guarantee that chromatographic column inside communicates with ambient atmosphere, avoids causing the static of flowing phase not circulate; The lower end of lid is an outer frosted tube wall, and with the interior frosted tube wall precision-fit of cylinder opening, be tightly connected, can realize pressurization to chromatographic column inside.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the whole structural scheme of mechanism of the utility model.
Among Fig. 1: 1. lid, 2. breather pipe, 3. drain pipe, 4. live valve, 5. cylinder.
The specific embodiment
In Fig. 1, a kind of chromatographic column lid with breather pipe comprises lid 1, breather pipe 2, drain pipe 3, live valve 4 and cylinder 5; This chromatographic column lid has the cylinder 5 of a tubular; The bottom of cylinder 5 is the drain pipe 3 of a band valve 4 alive, and cylinder 5 tops are the fluid reservoir of a diameter greater than cylinder 5, and the opening of a unlimited diameter less than cylinder 5 arranged at fluid reservoir top; Mate the lid 1 of the hollow that a top bending is installed with opening; The installation that is complementary of the diameter of lid 1 lower end and opening diameter, the front end of lid 1 has opening, and opening is installed with a penetrating breather pipe 2 that straight-through lid is terminal.During use, this lid 1 cooperates installation to get final product with cylinder 5 openings.
When using the utility model to carry out the separating experiment of mixture, populated needed fixedly phase adds after the mixture and flowing phase to be separated, and opens valve 4 alive, adds upper cover body 1 afterwards and can prevent that dust falls into chromatographic column in the air.
In Fig. 1, the lower end of this lid 1 is outer frosted tube wall, and with the interior frosted tube wall precision-fit of cylinder 5 openings, be tightly connected.When needs increase the chromatographic column pressure inside, breather pipe 2 is connected with the pressue device of outside gets final product.
