Description

Convertible matrix solid phase extraction equipment

[technical field]

The utility model relates to a kind of equipment of chemical industry, is the matrix solid phase extraction equipment that can do 180 ° of upsets and location.

[background technology]

Single glass-tube solid-phase extraction column commonly used, very fast with the process of eluant, eluent flushing to a kind of sample, but it is longer, consuming time in biased sample need to be changed into the waiting process of another kind of eluant, eluent flushing, often in order to save time sample extraction is separated not exclusively.For the extraction of batch samples or the flushing of multiple eluant, eluent, waiting process is longer, and extract and separate is more incomplete.It is more to expend time in general solid-phase extraction column, the longer situation of column length unreal in matrix in the laboratory at present, and separating power is difficult to reach re-set target, is difficult to finish the extracting and enriching of high efficiency short time.As if can make 180 ° in cylinder work overturn and locate respectively by adopting, add the eluant, eluent flushing in two-port respectively, vibrate in conjunction with oscillator, the special equipment of raising extract and separate speed has no report.

[utility model content]

The technical problems to be solved in the utility model provides a kind of matrix solid phase extraction equipment that can do 180 ° of upsets and locate respectively.

Solving the problems of the technologies described above the technical scheme that adopts is: this convertible matrix solid phase extraction equipment, comprise the sieve plate in extraction column and the cylinder thereof, matrix and support, the cylinder of extraction column is fusiformis, be inserted in the up-hole plate and orifice plate with a plurality of jacks, there is a supporting geometrical clamp bottom surface of each jack of up-hole plate or orifice plate, the both end sides of up-hole plate and orifice plate has side plate, the minor axis that has level to install on the central point of left side plate, the lockhole vertical with this axle arranged on the exposed junction of minor axis, have the screw that vertically cooperates with lock(ing) bolt on cross tube two free-ends of support, have horizontal minor axis patchhole on the section, after minor axis inserted this hole, its lockhole cooperated with lock(ing) bolt.

Up and down two port outer walls of described fusiformis cylinder are the frosted wall.

The beneficial effects of the utility model are by the extraction cartridge to perpendicular positioning, do 180 ° of secondary location of overturning again, the suitable for reading and end opening of cylinder is exchanged, two mouthfuls all can be poured eluant, eluent in cylinder, when need replacing eluant, eluent separates another kind of material, just saved the time of waiting for, realized that Rapid Extraction separates, and vibrates in conjunction with oscillator again, increase the power on the horizontal direction, make separation more thorough, save extraction time, improve extraction efficiency.

[specific embodiment]

The utility model is described in detail below in conjunction with example and with reference to accompanying drawing: referring to accompanying drawing, this convertible matrix solid phase extraction equipment, comprise the sieve plate 8 in extraction column and the cylinder thereof, matrix and support 1, the cylinder 5 of extraction column is fusiformis, be inserted in the up-hole plate 6 and orifice plate 7 with a plurality of jacks 11, there is a supporting geometrical clamp 4 bottom surface of each jack 11 of up-hole plate 6 or orifice plate 7, the both end sides of up-hole plate and orifice plate has side plate 9, the minor axis 2 that has level to install on the central point of left side plate, the lockhole vertical with this axle 2 arranged on the exposed junction of minor axis, have the screw 10 that vertically cooperates with lock(ing) bolt 3 on cross tube two free-ends of support 1, have horizontal minor axis 2 patchholes on the section, after minor axis inserted this hole, its lockhole cooperated with lock(ing) bolt 3, and up and down two port outer walls of fusiformis cylinder 5 are the frosted wall.During use, first with sample and solid matter etc. by experimental design requirement proportioning, being ground to uniform particles makes it be fit to do matrix, first a sieve plate 8 is placed cylinder 5 bottoms, add solid matrix at sieve plate 8, rap cylinder, make matrix top maintenance level and tamp even, put into another piece sieve plate, 5 upper and lower port places clog with the modular connection plug at cylinder, cylinder 5 are inserted in the jack 11 of up-hole plate 6 and orifice plate 7, tighten lock(ing) bolt 3, and clamp cylinder 5 with geometrical clamp 4, take off with the modular connection plug end opening place cylinder 5 is suitable for reading, respectively over against eluant, eluent container end opening with to connect the liquid bottle suitable for reading, open eluant, eluent container control valve, coutroi velocity connects the liquid bottle and collects leacheate, blows concentrated constant volume through nitrogen and finishes extracting and enriching.After a kind of separating substances is complete, suitable for reading and end opening moves apart eluant, eluent container end opening and connects the liquid bottle suitable for reading with cylinder 5, distinguish again again modular connection plug beyond the Great Wall, unscrew lock(ing) bolt 3, Rotate 180 °, up-hole plate 6 and orifice plate 7 are put upside down, cylinder is vertical again, tightens lock(ing) bolt 3, and the modular connection plug with cylinder 5 on the suitable for reading and end opening takes off, respectively over against the eluant, eluent container end opening that newly changes with newly to connect the liquid bottle suitable for reading, what add in the eluant, eluent container is another kind of eluant, eluent, opens control valve, coutroi velocity, connect the liquid bottle and collect new leacheate, after nitrogen blows concentrated constant volume, just finished extracting and enriching work again.

If this device is put into oscillator, in vibration, extract, can extract more thoroughly, more save time.But this also needs the outer wall of the up and down two-port of fusiformis cylinder 5 is made the frosted wall, with the interior frosted wall coupling that connects the liquid bottleneck.The end opening of eluant, eluent container is inserted the port of this fusiformis cylinder 5 than the depths, also this device and eluant, eluent container and the mutual alignment that meets liquid bottle three should be fixed, these can relate to the improvement of vibration frame and connect the improvement of liquid bottle, and are irrelevant with the application's theme, do not give unnecessary details.
