Abstract

The utility model provides a kind of solid-phase micro-extracting device, this device comprises: handle and be arranged on the collet that handle one end and handle realize linking, when operating grip makes collet open, can take out or put into extracting head, when operating grip makes collet shrink, collet clamping extracting head, makes extracting head and collet and handle be fixed as one.Solid-phase micro-extracting device described in the utility model, by arranging a collet between handle and extracting head, makes extracting head replaceable.The solid-phase micro-extracting device of replaceable extracting head, decreasing the time spent because waiting for extracting head activation, improve testing efficiency.In addition, when if desired recycling extracting head, only need to activate independent extracting head, compared with the extraction equipment with fixed extractor head in prior art, the activating apparatus of a constant volume can activate more independent extracting head.

Description

Solid-phase micro-extracting device
Technical field
The utility model relates to extraction equipment technical field, particularly relates to a kind of solid phase micro-extraction technique.
Background technology
Solid phase micro-extraction technique is the Sample Pretreatment Technique risen the nineties in 20th century, it is a kind of micro-extraction isolation technics grown up in solid phase extraction techniques, a kind of centralized procurement collection, extraction, the solvent-free sample micro-extraction new technology that concentrated and sample introduction is integrated.The research group that this technology is taught by the Pawliszyn of Canadian Waterloo university at first developed research first in 1989, belonged to non-solvent selective extraction method.
Compared with solid phase extraction techniques, SPME is simple to operate, easy to carry, low cost, overcomes that organic efficiency in solid phase extraction techniques is low, the susceptible to plugging drawback in adsorbent duct.Current solid phase micro-extraction technique is widely applied in sample pre-treatments.
Solid-phase micro-extracting device of the prior art is made up 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 adsorbent.Extracting head is connected with stainless steel wire, and outer surface cover has stainless steel tube, is not fractureed for the protection of quartz fibre.Stainless steel tube can penetrate rubber or plastic spacer carries out sampling 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, often need activate extracting head cost time a few hours before each use, this directly affects testing efficiency.In addition, in extracting head activation process, because the volume of activating apparatus limits, an activating apparatus is merely able to the solid-phase micro-extracting device of activation two band extracting head at every turn.
Utility model content
For this reason, technical problem to be solved in the utility model is: provide a kind of solid-phase micro-extracting device, makes the extracting head in this solid-phase micro-extracting device replaceable.
The utility model provides a kind of solid-phase micro-extracting device, this device comprises: handle and be arranged on the collet that handle one end and handle realize linking, when operating grip makes collet open, can take out or put into extracting head, when operating grip makes collet shrink, collet clamping extracting head, makes extracting head and collet and handle be fixed as one.
Wherein, in described extracting head, plating has extraction Stationary liquid.
Described extracting head is the thin rod of plating with extraction Stationary liquid.
Solid-phase micro-extracting device described in the utility model, by arranging a collet between handle and extracting head, makes extracting head replaceable.The solid-phase micro-extracting device of replaceable extracting head, decreasing the time spent because waiting for extracting head activation, improve testing efficiency.In addition, when if desired recycling extracting head, only need to activate independent extracting head, compared with the extraction equipment with fixed extractor head 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 described in the utility model;
Fig. 2 is the structural representation when extracting head of solid-phase micro-extracting device shown in Fig. 1 is separated with elastic clip;
Fig. 3 is structural representation extracting head being put into activating apparatus.
Detailed description of the invention
Below, by reference to the accompanying drawings the utility model is described in detail.
As shown in Figure 1, present embodiments provide a kind of solid-phase micro-extracting device, this device comprises: handle 11 and be arranged on the collet 12 that handle 11 one end and handle 11 realize linking, when operating grip 11 makes collet 12 open, can take out or put into extracting head 13, when operating grip makes collet 12 shrink, 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 get final product opening and contraction of operating flexibility chuck 12 by control handle 11.When collet 12 opens, can take out extracting head 13 or insert extracting head 13, when collet 12 shrinks, can by clamping for extracting head 13 live, extracting head 13 and collet 12 and handle 11 are fixed as one.
In extracting head 13, plating is with extraction Stationary liquid, and extracting head 13 is to plate the thin rod with extraction Stationary liquid.In general extracting head, plating is with PDMS, PA etc.Extraction Stationary liquid is a kind of phase maintaining static in extraction, sample is produced to absorption, is namely plated in a kind of film of thin nose.
In order to the impurity desorb extracting Stationary liquid absorption in process of production is not destroyed extraction Stationary liquid itself, the special activating apparatus 20 pairs of extracting head 13 of general use activate, can the extraction equipment two of activation zone fixed extractor head if activating apparatus 20 is disposable, so this same activating apparatus 20 is disposable can activate independent extracting head tens of described in the present embodiment, improves activation efficiency.
Extracting head after having activated, can pack separately, sell.
Removable extracting head, for avoiding cross pollution, can single use, 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 arranging a collet between handle and extracting head, makes extracting head replaceable.The solid-phase micro-extracting device of replaceable extracting head, decreasing the time spent because waiting for extracting head activation, improve testing efficiency.In addition, when if desired recycling extracting head, only need to activate extracting head, compared with the extraction equipment with fixed extractor head 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 utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
