Description
Technical field
The utility model relates to the chemical analysis technology field, specifically, relates to a kind of SPE optimization device.
Background technology
SPE (Solid-Phase Extraction, SPE) is the sorption extraction process of a kind of absorption-washing-wash-out, is a kind of sample pretreatment technology, can separate sample, purifying and concentrated.Solid phase is larger than the solvent of separated and dissolved thing to the absorption affinity of separator, compares with liquid-liquid extraction method and has improved the object rate of recovery, can more effectively object be separated with chaff interference.Therefore, solid phase extraction techniques is widely used in the various aspects such as environment measuring analysis, food analysis, Pharmaceutical Analysis.
The SPE operating process comprises activation, application of sample, cleaning filler, wash-out determinand step.Solid-phase extraction column sub-volumes of the prior art is little, and in elution process, if untimely interpolation eluent, the pillar filler just is exposed in the air easily, even dry, has a strong impact on the absorption of sample-washing-elute effect; Solid-phase extraction device in the market is expensive, versatility is poor, and the application of solid phase extraction techniques is restricted.
The utility model content
The purpose of this utility model provides a kind of SPE optimization device, adds the problem that dries up easily in the untimely situation and the problem that solid-phase extraction device is expensive, versatility is poor to solve solid-phase extraction column at eluent.
For achieving the above object, the technical scheme taked of the utility model is: a kind of SPE optimization device is provided.This device comprises solid-phase extraction column, disk collector, support, pipe clamp.This extraction equipment also comprises the siphon syringe needle, and described siphon syringe needle is connected in the bottom of solid-phase extraction column, and solid-phase extraction column is fixed on the support upper part by pipe clamp, and the support end portion is fixed in disk collector center bottom.
Described siphon syringe needle is bent upwards, and the peak place is provided with stubborn valve, and peak is than the upper sieve plate hight 0.5cm of solid-phase extraction column.
Described disk collector can rotate, and which is provided with according to the evenly distributed test tube hole of annular array, and test tube hole and siphon syringe needle are on same circumference.
Described siphon syringe needle is made by stainless steel.
Described solid-phase extraction column inside is provided with up and down two-layer sieve plate, and sieve plate is the material of anti-organic corrosion; The filler of described solid-phase extraction column is selected from a kind of in C18, C8, active carbon, diatomite, aluminium oxide, magnesium silicate, polymer, ion-exchanger, exclusion chromatography filler, the affinity chromatograph filling; Described solid-phase extraction column pillar material is polypropylene for medical article.
Solid-phase extraction column outlet at bottom place is connected to the siphon syringe needle, and the siphon syringe needle is bent upwards, and is provided with stubborn valve at the peak place, and siphon syringe needle peak goes out 0.5cm than solid-phase extraction column upper sieve plate hight.When the eluent liquid level was higher than the peak of siphon syringe needle in the solid-phase extraction column, stubborn valve was opened, and eluent can flow out gradually, regulated stubborn valve and can control elution speed; When the eluent liquid level is lower than the peak of siphon syringe needle in the solid-phase extraction column, in the siphon syringe needle eluent liquid level will with solid-phase extraction column in liquid level be consistent, eluent can not flow out.Because the peak of siphon syringe needle than solid-phase extraction column at the middle and upper levels sieve plate exceed 0.5cm, so elution process at the middle and upper levels sieve plate can not be exposed in the air, dry-out more can not occur in solid-phase extraction column.Can control the height of solid-phase extraction column by regulating pipe clamp.The disk collector can rotate, and the test tube hole and the siphon syringe needle that arrange on it remain on the same circumference, make things convenient for the collection of eluent.
The utility model advantage is: in the sample elution process, use siphon principle, avoid solid-phase extraction column dry, the impact experiment; The utility model solid-phase extraction device structure is easy, simple to operate, with low cost, has improved the versatility of solid-phase extraction device.
Description of drawings
The Reference numeral and the part that relate in the accompanying drawing are as follows:
1. disk collector 11. test tube holes
2. support 3. pipe clamps
4. solid-phase extraction column 41. upper sieve plates
42. lower sieve plate 43. fillers
5. siphon syringe needle 51. is twisted valve.
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
Please refer to Fig. 1, Fig. 1 is the overall structure schematic diagram of the utility model SPE optimization device.Described SPE optimization device comprises solid-phase extraction column 4, disk collector 1, support 2, pipe clamp 3, and described device also comprises siphon syringe needle 5.Siphon syringe needle 5 is connected to the outlet at bottom place of solid-phase extraction column 4, and solid-phase extraction column 4 is fixed in the upper end of support 2 by pipe clamp 3, and the end portion of support 2 is fixed in the center bottom of disk collector 1.
Can control the height of solid-phase extraction column 4 by regulating pipe clamp 3.Disk collector 1 can rotate, and which is provided with according to the evenly distributed test tube hole 11 of annular array, and test tube hole 11 remains on the same circumference with siphon syringe needle 5, makes things convenient for the collection of eluent.Solid-phase extraction column 4 inside are provided with upper sieve plate 41 and lower sieve plate 42, are equipped with filler 43 between upper sieve plate 41 and lower sieve plate 42.Siphon syringe needle 5 is bent upwards, and is provided with at the peak place to twist valve 51, and siphon syringe needle 5 peaks exceed 0.5cm than the upper sieve plate 41 in the solid-phase extraction column 4.
Operation principle: in the sample elution process of SPE operation, when the eluent liquid level is higher than the peak of siphon syringe needle 5 in the solid-phase extraction column 4, twists valve 51 and open, eluent can flow out gradually, regulates stubborn valve 51 and can control elution speed; In case the eluent liquid level is lower than the peak of siphon syringe needle 5 in the solid-phase extraction column 4, in the siphon syringe needle 5 the eluent liquid level will with solid-phase extraction column 4 in liquid level be consistent, and eluent can not flow out.Because the peak of siphon syringe needle 5 exceeds 0.5cm than the upper sieve plate 41 in the solid-phase extraction column 4, so even the eluent interpolation is untimely in elution process, upper sieve plate 41 can not be exposed in the air yet, dry-out more can not occur in solid-phase extraction column 4.
Need to prove that in the extraction optimization device of present embodiment, the upper sieve plate 41 in the solid-phase extraction column 4 and lower sieve plate 42 are the material of anti-organic corrosion; Filler 43 can be in C18, C8, active carbon, diatomite, aluminium oxide, magnesium silicate, polymer, ion-exchanger, exclusion chromatography filler or the affinity chromatograph filling a kind of; The pillar material of solid-phase extraction column 4 is polypropylene for medical article.This solid-phase extraction device structure is easy, simple to operate, with low cost, has versatility.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
