Abstract
The utility model discloses a solid-phase extracting device capable of being switched on line. The solid-phase extracting device comprises a casing, an upper cover and a rotatable supporting stand, wherein the circle center of the upper cover is provided with a center hole, 4-12 small holes which are connected with an SPE column are arranged on a circumstance which utilizes the center hole as the centre of circle and has a certain radius in equal angle, a pumping hole pipe and an exhaust valve are further arranged on the upper cover, the supporting stand is a rotatable supporting stand, and comprises an upper, a middle and a lower circular discs which have the same diameters and are up and down arrayed in a certain distance and whose centers are provided with center holes, a circular disc supporting stand which is connected with the circular discs and is connected with a threaded rod, and a center rotary shaft, a receiving pipe for holding sample liquid and a waste liquid receiving pipe hole which are vertical and correspond to SPE column connecting holes on the upper cover are staggered on the upper round disc and the middle round disc, the center rotary shaft penetrates through the center hole of the upper cover, and further penetrates through the center holes of the upper disc, the middle disc and the lower disc, and is connected into a whole. The solid-phase extracting device can simultaneously process a plurality of samples, can achieve convenient control to flow speed, can be switched on line, is convenient for collecting eluent, and is simple and convenient to use.
Description
Technical field
The utility model relates to solid-phase extraction device, specifically is a kind of solid-phase extraction device that can online switching.
Background technology
Present SPE device, it is the SPE device that uses with the SPE column kit, comprise transparent shell, internal stent, aspirating hole, this SPE device can not be realized the online switching between sample liquid receiving tube and the waste liquid receiving tube, and cost an arm and a leg, realize switching, must recover normal pressure, open loam cake, when taking a lot of work.
The utility model content
The purpose of this utility model is that a kind of low price will be provided, and is easy to use, can handle a plurality of samples simultaneously, can realize the solid-phase extraction device of online switching between eluent pipe and the discarded liquid pipe.
The utility model comprises transparent shell, be arranged on the loam cake on the housing port and be arranged on the interior support of housing, unlike the prior art be: the position, the center of circle of described loam cake is provided with the centre bore equipped with central rotating shaft, be that equal angles is provided with 4-12 aperture that is connected with the SPE post on the circumference of center of circle certain radius with the centre bore, also be provided with aspirating hole pipe and air bleeding valve last covering, described support is a swinging mounting, by last, in, following three diameters are identical, central authorities are provided with centre bore and the disk that is arranged above and below at regular intervals and disc holder connecting screw rod that is attached thereto and central rotating shaft composition, last, in be crisscross arranged on two disks with on the SPE post that covers connect vertical corresponding placement sample liquid receiving tube of aperture and waste liquid reception pore, central rotating shaft passes the loam cake centre bore, penetrates again, in, the centre bore of following three disks is connected as a single entity.
Disk proximal edge place, described upper, middle and lower equidistantly is provided with 3 equipped with 3 support connecting screw rods respectively circular holes, and wherein the centre bore of lower disc is a rectangle, and described support connecting screw rod is provided with the limit screw cap or the limit casing of fixed disc.

Description of drawings
Fig. 1 for the utility model can online switching solid-phase extraction device structure major part schematic diagram.
The specific embodiment
The utility model is made up of transparent shell 1, loam cake 2, rotatable support 3, loam cake 2 circle centre positions are provided with centre bore 2-1, vertically pass for central rotating shaft 3-1, centre bore 2-1 is provided with sealing ring, centre bore 2-1 with loam cake 2 is on the circumference of center of circle certain radius, and equal angles is provided with 4-12 aperture 2-2 that mates with the SPE column cap, in addition, also be provided with air extraction connector 2-3, air bleeding valve 2-4 on the loam cake 2, be provided with sealing gasket 2-5 between loam cake 2 and the housing 1.
The central rotating shaft 3-1 that has handle passes the centre bore 2-1 of loam cake 2, penetrates the centre bore 3-5 of three the disk 3-2 in upper, middle and lower again, drives rotatable support 3 and rotates.
During use, on support, place receiving vessel, build loam cake, lay SPE pillar or plug, be in closed state inside and outside making this device, open external aspiration pump, under negative pressure state, at the outside rotation of device central rotating shaft, make the relative loam cake aperture of device inner support and receiving tube and on extraction column be subjected to displacement, reach the purpose of switching extract, eluent.
This device has improved the repeatability of SPE by online steady switching receiving tube/bottle under the negative pressure state, uniformity, thus improved analytical precision and reliability, improved SPE efficient.
