The invention discloses a solid-phase micro-extraction device. The solid-phase micro-extraction device comprises a pushing rod and an extraction head which is connected with the pushing rod, wherein the pushing rod is detachably connected with the extraction head; the pushing rod is arranged in a pushing cylinder in a sleeving manner; the pushing rod is capable of moving in an axial direction of the pushing cylinder, and is extended out of one opening of the pushing cylinder; an outer-layer support protective tube is arranged outside the pushing cylinder in a sleeving manner; one end of the outer-layer support protective tube is connected with the pushing cylinder, and the pushing cylinder is capable of moving in an axial direction of the outer-layer support protective tube; the extraction head is extended out of the other end of the outer-layer support protective tube. By innovating the structure of the conventional device, a handle part (comprising parts such as the pushing rod) is greatly simplified, so that the handle part has the characteristics of simplicity in assembly, easiness in replacement of the parts and replaceable extraction head and is compatible with commercial handles and extraction heads, thereby improving the using efficiency of the handle, saving the cost for repurchasing the handle when replacing the extraction handle and facilitating commercial production and popularization.
Description
Technical field
The present invention relates to a kind of solid-phase micro-extracting device.
Background technology
Along with complicated micro-example analysis becomes more and more general and important, sample preparation and pretreatment have become a requisite step, also be one of the most key step determining analysis result reliability, so development efficiently, sample-pretreating method just becomes the problem that analysis field must study and the target of pursuing all the time fast.SPME sample treatment can meet such requirement, and the core component of this processing method is handle and coating.At present once property and two types of repeatedly uses replaceable extracting head of commercialization handle.Disposable handle in use requires operation strict, at once loses use value if extracting head is damaged handle; Removable handle arrangement complexity, is used step trouble, need multistep operation, and this handle of two types is expensive, is unfavorable for the popularization of method.
Summary of the invention
The object of this invention is to provide a kind of solid-phase micro-extracting device, this device simple and convenient assembly, and parts (extracting head) are replaceable, have certain product promotion that has and are worth.
Solid-phase micro-extracting device provided by the present invention, comprises a push rod and the extracting head being connected with described push rod, between described push rod and described extracting head for removably connecting;
Described pushing rod sleeve is located in a pushing cylinder, and described push rod can be along the moving axially of described pushing cylinder, and described push rod extends from a port of described pushing cylinder;
The outer sheathed outer supportive protection pipe of described pushing cylinder, one end of described outer supportive protection pipe is connected with described pushing cylinder, and described pushing cylinder can moving axially along described outer supportive protection pipe; Described extracting head is extended from the another port of described outer supportive protection pipe.
In above-mentioned solid-phase micro-extracting device, between described push rod and described extracting head, specifically can be threaded, flange is connected, socket joint connects, bite type connects or clamp connection, can play the effect of universal connection, therefore extracting head described in the present invention can be changed, and the parts such as push rod are can be reusable.
In above-mentioned solid-phase micro-extracting device, described extracting head is coated with extracting head protection tube, and is provided with ring cavity between described extracting head and described extracting head protection tube, and described extracting head protection tube, for the protection of described extracting head, can adopt stainless steel tube.
In above-mentioned solid-phase micro-extracting device, one end of described extracting head protection tube is connected with one end of pushing cylinder, can realize stretching out and withdrawal of described extracting head protection tube by described push rod.
In solid-phase micro-extracting device of the present invention, described push rod and described pushing cylinder all can adopt polyvinylchloride plastic tube; Described extracting head protection tube can adopt stainless steel tube; Described extracting head can be quartz fibre or the stainless steel wire of certain thickness; Described outer supportive protection pipe body can adopt the material of high temperature type, as aluminum pipe; Described air packing can be silicon rubber.
Solid-phase micro-extracting device of the present invention, structure to prior device is innovated, handle portion (parts such as push rod) has carried out large simplification, the structures such as Z-gathering sill, O type circle, visual windows, spring and the positioning threads of traditional design are cancelled, handle portion have that easy assembled, parts are easily changed and the removable feature of extracting head and with commercialization handle and extracting head compatibility, thereby increase the service efficiency of handle, save replacing extracting head and need to again buy the cost of handle, and be convenient to commercially produce popularization.
