Description
Technical field
The utility model relates to the impurity absorption type purifier of sample extracting solution in a kind of food safety detection, is specifically related to a kind of miniature decontaminating column of impurity absorption type of pipettor direct injected.
Background technology
At present, solid-phase extraction column is that the one that in food safety detection, sample extracting solution purifies commonly uses purifier.Known solid-phase extraction column is made up of column jecket, sieve plate and filler, and impurity absorption and object can be divided into adsorb two types, is usually designed to 3ml and 6ml two kinds of specifications, is applicable to the purification of constant sample extracting solution and concentrates.But, along with the development of new type purification material particularly impurity absorption technology, a lot of object is detected and can accomplish machine in direct purification, and common solid-phase extraction column needs supporting negative pressure or malleation extraction equipment in use, operating process more complicated, the filler that purification process expends and solution more, cause certain wasting of resources and environmental pollution; And common solid-phase extraction column can only accomplish purification, can not large granular impurity in filtering solution.
Utility model content
The purpose of this utility model is to provide a kind of miniature decontaminating column of impurity absorption type of pipettor direct injected, the utility model can directly use pipettor to carry out pressurization sample introduction, purification and filtered sample extract rapidly, do not need other any equipment, greatly simplifie operating procedure, overcome the deficiency that common SPE column volume is comparatively large, need special equipment, operating process loaded down with trivial details.
The miniature decontaminating column of impurity absorption type of pipettor direct injected provided by the utility model, comprises a column jecket;
One end of described column jecket is communicated with a drain pipe, and nearly described fluid pipe end, be provided with upper sieve plate and lower sieve plate in described column jecket, between described upper sieve plate and described lower sieve plate, be filled with filler, between described filler and described lower sieve plate, be provided with filter membrane;
The other end of described column jecket is provided with plug, and described plug is provided with sample holes.
In the described miniature decontaminating column of impurity absorption type, described plug can be rubber stopper, assembles more convenient;
Described sample holes is located at the middle part of described rubber stopper.
In the described miniature decontaminating column of impurity absorption type, described upper sieve plate, described lower sieve plate and be interference fit between described plug and described column jecket.
In the described miniature decontaminating column of impurity absorption type, the aperture of described upper sieve plate and described lower sieve plate is all less than the particle diameter of described filler, in order to avoid described filler oozes out.
In the described miniature decontaminating column of impurity absorption type, the thickness of described filter membrane can be 100 ~ 200 microns.
The miniature decontaminating column of impurity absorption type of the utility model pipettor direct injected has following beneficial effect:
The utility model does not need specific necessary instrument equipment, can complete purification and the filter process of impurity absorption pattern in food safety detection by means of only a simple mechanism simultaneously, and simple to operate, quick, and volume is little, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the miniature decontaminating column of impurity absorption type of the utility model pipettor direct injected.
In figure, each mark is as follows:
1 sample holes, 2 column jeckets, 3 rubber stoppers, 4 upper sieve plates, 5 fillers, 6 filter membranes, 7 times sieve plates, 8 drain pipes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, be the structural representation of the miniature decontaminating column of impurity absorption type of the utility model pipettor direct injected, it comprises the column jecket 2 of a high purity polypropylene material, and one end of column jecket 2 is communicated with drain pipe 8, for the outflow of liquid.Near drain pipe 8 end is set, the upper sieve plate 4 of high-molecular polythene material and the lower sieve plate 7 of high-molecular polythene material is provided with in column jecket 2, and between upper sieve plate 4 and lower sieve plate 7, be filled with the filler 5 of the spherical end-blocking C18 of high-purity and acidic alumina mixing, its aperture is greater than the aperture of upper sieve plate 4 and lower sieve plate 7, in order to avoid it oozes out from upper sieve plate 4 and lower sieve plate 7.Be provided with filter membrane 6 between filler 5 and lower sieve plate 7, its aperture will be not more than 0.22 μm, and to meet the detecting instrument sample introduction requirements such as high performance liquid chromatography, its thickness is 100 ~ 200 microns.The other end (holding relative end with arranging of drain pipe 8) of column jecket 2 is provided with rubber stopper 3, to close column jecket 2.Be provided with sample holes 1 in the centre of rubber stopper 3, the diameter of sample holes 1 is 2mm, to meet the requirement of pipettor gun head direct injected.
In the miniature decontaminating column of the utility model impurity absorption type, ensure rubber stopper 3, upper sieve plate 4 and be interference fit between lower sieve plate 7 and column jecket 2, thus rely on this over pressure to firmly fix rubber stopper 3, upper sieve plate 4 and lower sieve plate 7, and then be sealed and matched with column jecket 2.
When using the miniature decontaminating column of the impurity absorption type of the utility model pipettor direct injected, can carry out in accordance with the following steps:
During use, existing being placed in by miniature for the utility model decontaminating column connects on sample bottleneck, the rifle head inhaling the pipettor having sample extracting solution to be clean is aimed at and inserts sample holes 1, pressing pipettor control button forms malleation, sample extracting solution is made successively by sample holes 1, upper sieve plate 4, filler 5, filter membrane 6 and lower sieve plate 7 under the double action of malleation and gravity, then enter along drain pipe 8 and connect in sample bottle, thus reach the object to sample extracting solution fast purification and filtration.
