Abstract
The invention provides a solid-phase micro-extraction device which comprises a handle and an elastic collet, wherein the elastic collet is arranged at one end of the handle and is linked with the handle; when the elastic collet is opened by operating the handle, an extraction head can be taken out from or put into the elastic collet; and when the elastic collet is shrunk by operating the handle, the extraction head is clamped by the elastic collet, so that the extraction head, the elastic collet and the handle are fixed into a whole. According to the solid-phase micro-extraction device, the elastic collet is arranged between the handle and the extraction head, so that the extraction head can be replaced. The extraction head of the solid-phase micro-extraction device can be replaced, so that the time spent on waiting the activation of the extraction head can be shortened, and the testing efficiency is increased. Furthermore, if the extraction head is required to be recycled, the extraction head is only required to be activated separately; and compared with an extraction device provided with a fixed extraction head in the prior art, the solid-phase micro-extraction device enables a relatively large quantity of single extraction heads to be activated by an activation device with a certain volume.
Description
Technical field
The present invention relates to extraction equipment technical field, relate in particular to a kind of solid phase micro-extraction technique.
Background technology
Solid phase micro-extraction technique is the Sample Pretreatment Technique rising the nineties in 20th century, it is a kind of micro-extraction isolation technics growing up in solid phase extraction techniques, a kind of centralized procurement collection, extraction, the concentrated solvent-free sample micro-extraction new technology being integrated with sample introduction.This technology was developed research by the Pawliszyn professor's of Canadian Waterloo university research group in 1989 at first first, belonged to non-solvent selective extraction method.
Compare with solid phase extraction techniques, SPME is simple to operate, easy to carry, and expense is cheap, has overcome in solid phase extraction techniques that organic efficiency is low, the susceptible to plugging drawback in adsorbent duct.Solid phase micro-extraction technique is widely applied in sample pre-treatments at present.
Solid-phase micro-extracting device of the prior art consists of handle and the extracting head that is arranged on handle one end, and extracting head is 1 centimeter length, scribbles the vitreous silica fiber of different adsorbents.Extracting head is connected with stainless steel wire, and outer surface cover has stainless steel tube, for the protection of quartz fibre, is not fractureed.Stainless steel tube can penetrate rubber or plastic spacer samples or sample introduction.
Because the extracting head in solid-phase micro-extracting device in prior art is fixedly connected on handle, non-exchange, for saving testing cost, extracting head is usually reused.For avoiding cross pollution, before each use, often need to spend the time a few hours extracting head is activated, this has directly affected testing efficiency.In addition,, in extracting head activation process, due to the capacity limitation of activating apparatus, an activating apparatus is merely able to activate two with the solid-phase micro-extracting device of extracting head at every turn.
Summary of the invention
For this reason, technical problem to be solved by this invention is: a kind of solid-phase micro-extracting device is provided, makes the extracting head in this solid-phase micro-extracting device replaceable.
The invention provides a kind of solid-phase micro-extracting device, this device comprises: handle and be arranged on handle one end and handle is realized the collet of interlock, when operating grip opens collet, can take out or put into extracting head, when operating grip shrinks collet, collet clamps extracting head, and extracting head and collet and handle are fixed as one.
Wherein, in described extracting head, plating has fixedly phase of extraction.
Described extracting head is for plating is with extracting the fixedly thin rod of phase.
Solid-phase micro-extracting device of the present invention, by a collet is set between handle and extracting head, makes extracting head replaceable.The solid-phase micro-extracting device of replaceable extracting head, has reduced the time because waiting for that extracting head activation spends, and has improved testing efficiency.In addition, while if desired recycling extracting head, only need independent extracting head to activate, and with the extraction equipment of fixed extractor head, compare in prior art, the activating apparatus of a constant volume can activate more independent extracting head.
Accompanying drawing explanation
Fig. 1 is the structural representation of solid-phase micro-extracting device of the present invention;
Fig. 2 is structural representation when solid-phase micro-extracting device extracting head is separated with elastic clip shown in Fig. 1;
Fig. 3 is for putting into extracting head the structural representation of activating apparatus.
The specific embodiment
Below, describe the present invention by reference to the accompanying drawings.
As shown in Figure 1, the present embodiment provides a kind of solid-phase micro-extracting device, this device comprises: handle 11 and be arranged on handle 11 one end and handle 11 is realized the collet 12 of interlock, when operating grip 11 opens collet 12, can take out or put into extracting head 13, when operating grip shrinks collet 12, collet 12 can clamp extracting head 13, and extracting head 13 and collet 12 and handle 11 are fixed as one.
That is, collet 12 and handle 11 can link, and by control handle 11, get final product opening and contraction of operating flexibility chuck 12.When collet 12 opens, can take out extracting head 13 or insert extracting head 13, when collet 12 shrinks, can extracting head 13 is clamping firmly, extracting head 13 and collet 12 and handle 11 are fixed as one.
In extracting head 13, plating is with extracting fixedly phase, and extracting head 13 has the fixedly thin rod of phase of extraction for plating.In general extracting head, plating is with PDMS, PA etc.Extraction is fixing is a kind of phase that maintains static in extraction, sample is produced to absorption mutually, is plated in a kind of film of thin nose.
For the impurity desorb of fixing absorption mutually will be extracted in process of production, do not destroy extraction fixing own mutually, the special 20 pairs of extracting head 13 of activating apparatus of general use activate, if disposable two of the extraction equipments that can activation zone fixed extractor head of activating apparatus 20, disposable tens of of the extracting head that can activate described in the present embodiment separately of this same activating apparatus 20, have improved activation efficiency so.
Extracting head after having activated, can pack separately, sell.
Removable extracting head, for avoiding cross pollution, can disposablely be used, but for the not high test of quantitative test required precision, extracting head is reused after can again reclaiming activation.
Solid-phase micro-extracting device described in the present embodiment, by a collet is set between handle and extracting head, makes extracting head replaceable.The solid-phase micro-extracting device of replaceable extracting head, has reduced the time because waiting for that extracting head activation spends, and has improved testing efficiency.In addition, while if desired recycling extracting head, only need to activate extracting head, and with the extraction equipment of fixed extractor head, compare in prior art, the activating apparatus of a constant volume can activate more independent extracting head.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
