Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Referring to fig. 1-4, a filling apparatus for a solid-phase extraction column packing comprises a main board 1, wherein at least one sample-adding channel 2 is arranged on the main board 1, and a valve 3 is arranged at the bottom of the sample-adding channel 2.

In further detail, the main board 1 is further provided with a charging area 4, and the charging area 4 is used for placing fillers.

In further detail, the device also comprises a scraper 5, wherein the scraper 5 is used for scraping the filler in the loading area 4 into the loading channel 2, and the filler in the loading channel 2 is flush with the top of the loading channel 2.

More specifically, the squeegee 5 has a frame shape.

When the experimenter added the sample in the application of sample passageway 2, pour the filler into in reinforced district 4 earlier, reuse scraper blade 5 scrapes the filler in reinforced district 4 into application of sample passageway 2, strickles off with scraper blade 5 at last, makes filler and application of sample passageway 2 top in the application of sample passageway 2 flush. The volume of the sample adding channel 2 is fixed, so that the same amount of the filler added into the solid phase extraction column every time is ensured, and the consistency of the filler is ensured.

In further detail, the length of the sample adding channel 2 is greater than the thickness of the main board 1, and the top of the sample adding channel 2 is flush with the main board 1.

In further detail, the number of the loading channels 2 is at least two. This setting can realize reaching once operation multitube filling effect, can carry out the filling of a plurality of solid phase extraction posts simultaneously. Thereby improving the production efficiency on the premise of ensuring the quality.

In further detail, the valve 3 is a movable cover member.

In further detail, application of sample passageway 2 and apron spare are articulated, application of sample passageway 2 the bottom be provided with sealing washer 8 and be used for adsorbing magnet 6 of apron spare, the rotatable application of sample passageway 2 that opens of apron spare. When the valve 3 is closed, the magnet 6 at the bottom of the sample adding channel 2 attracts the cover plate member, so that the bottom of the sample adding channel 2 is closed. The cover member may be made of a magnetic material that can be attracted by the magnet 6. The experimenter can break the cover plate member off with the fingers and thumb so that the cover plate member rotates to open the sample adding channel 2. The sealing ring 8 is used for improving the sealing performance between the cover plate member and the sample adding channel 2.

In further detail, the device also comprises a sample adding control part 7, wherein the sample adding control part 7 is sleeved at the lower end of the sample adding channel 2, the sample adding control part 7 can move along the length direction of the sample adding channel 2, and the sample adding control part 7 is used for changing the sample adding amount of the filler. The sample adding control part 7 is sleeved at the lower end of the sample adding channel 2 and can be in threaded rotary connection with the sample adding channel 2. The sample application control member 7 is equivalent to lengthening the length of the sample application channel 2, so that the loadable amount of the sample application channel 2 is increased. And the loading control member 7 can be moved along the length of the loading channel 2 to change the loadable volume. The experimenter can adjust the adding amount of the filler according to the requirement. When the sample adding control part 7 is installed, the valve 3 needs to be opened firstly and then the sample adding control part is installed. Thus, when the filler is filled, the filler is not blocked by the cover plate.
