Description
Technical field
The utility model relates to the decontaminating column of sample extracting solution in a kind of food safety detection, is specifically related to a kind of decontaminating column of extract direct injected.
Background technology
At present, a kind of common method of the pollutant monitorings such as food and agricultural product Pesticides, mycotoxin is exactly adopt decontaminating column device to adsorb the impurity in sample extracting solution, thus obtains the filtered fluid that can be used for instrument detection.But generally, decontaminating column is fixed by being suspended on the enterprising line position of test tube rack, and sample injection bottle carries out position by sample introduction bottle stand to be fixed, and the difference due to spacing size makes two kinds of stationary installations and do not match.The filtered fluid of sample extracting solution after decontaminating column purification can not directly enter in sample injection bottle, but needs separately to catch filtered fluid with a test tube at the liquid outlet of decontaminating column, and then transfers in sample injection bottle by filtered fluid, detects for use in instrument.This mode, not only adds the consumption of the experiment material such as test tube, transfer pipet, and filtered fluid is easily subject to the secondary pollution of contact material in transfer process.
Utility model content
The purpose of this utility model is to provide a kind of decontaminating column of extract direct injected, the utility model decontaminating column can make sample extracting solution by directly entering in sample injection bottle after this decontaminating column, thus complete sample purification fast and move liquid process, simplify operation steps, overcome during common purifying post uses and move the deficiency that the experiment material consumption of liquid process and filtered fluid are subject to contact material secondary pollution.
The decontaminating column of extract direct injected provided by the utility model, comprises a column jecket;
One end of described column jecket is communicated with a drain pipe, is provided with upper sieve plate and lower sieve plate, is filled with filler, is provided with filter membrane between described filler and described lower sieve plate between described upper sieve plate and described lower sieve plate in the described column jecket of described fluid pipe end;
In described fluid pipe end, described column jecket connects a sleeve pipe, and described drain pipe is located in described sleeve pipe.
In the decontaminating column of described extract direct injected, the length of described sleeve pipe is greater than the length of described drain pipe, and namely controlling described drain pipe can not extend in described sleeve pipe, like this, when carrying out sample introduction, described sleeve pipe is coordinated with sample injection bottle, ensure the safety of sample introduction.
In the decontaminating column of described extract direct injected, described upper sieve plate and be interference fit between described lower sieve plate and described column jecket.
In the decontaminating column of described extract direct injected, 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 decontaminating column of described extract direct injected, the thickness of described filter membrane is 100 ~ 200 microns.
The decontaminating column of the utility model extract direct injected has following beneficial effect:
The utility model decontaminating column can make sample extracting solution directly be entered in sample injection bottle by this decontaminating column, thus disposable sample purification and move liquid process, and simple to operate, quick, reduce the consumption of experiment material, avoid filtered fluid secondary pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the decontaminating column of the utility model extract direct injected.
In figure, each mark is as follows:
1 column jecket, 2 upper sieve plates, 3 fillers, 4 filter membranes, 5 times sieve plates, 6 drain pipes, 7 sleeve pipes.
Embodiment
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 decontaminating column of the utility model extract direct injected, it comprises the column jecket 1 of a high purity polypropylene material, and the internal diameter of column jecket 1 is 12 ~ 13mm.One end of column jecket 1 is communicated with drain pipe 6, for the outflow of liquid.Near drain pipe 6 end is set, the upper sieve plate 2 of high-molecular polythene material and the lower sieve plate 5 of high-molecular polythene material is provided with in column jecket 1, and between upper sieve plate 2 and lower sieve plate 5, be filled with the filler 3 of the spherical end-blocking C18 of high-purity and acidic alumina mixing, its aperture is greater than the aperture of upper sieve plate 2 and lower sieve plate 5, in order to avoid it oozes out from upper sieve plate 2 and lower sieve plate 5.Be provided with filter membrane 4 between filler 3 and lower sieve plate 5, 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.In fluid pipe end, column jecket 1 connects the sleeve pipe 7 that a length is 1.0 ~ 1.5cm, and drain pipe 1 is located in this sleeve pipe 7, and the material of sleeve pipe 7 is identical with the material of column jecket 1.Sample extracting solution is when this decontaminating column purifies, and drain pipe 6 is deeply in sample introduction bottleneck, and sleeve pipe 7 is enclosed within sample introduction bottleneck outer wall, and fix to meet decontaminating column position, filtered fluid flows into the requirement of sample injection bottle smoothly.
The utility model is got in the decontaminating column of liquid direct injected, ensure upper sieve plate 2 and be interference fit between lower sieve plate 5 and column jecket 1, thus relies on this over pressure to firmly fix sieve plate 2 and lower sieve plate 5, and then is sealed and matched with column jecket 2.
When using the utility model to get the decontaminating column of liquid direct injected, can carry out in accordance with the following steps:
Now the utility model decontaminating column is placed on sample introduction bottleneck by sleeve pipe 7 during use, sample extracting solution to be clean is had to join in column jecket 1 by inhaling, sample extracting solution is made successively by upper sieve plate 2, filler 3, filter membrane 4 and lower sieve plate 5 under the positive pressure of gravity or other modes, then enter along drain pipe 6 and connect in sample bottle, thus reach the object to sample extracting solution fast purification and filtration.
