Purification apparatus and method

1. A purification apparatus comprising:

a mobile phase distillation part for distilling a mobile phase;

a mobile phase liquefaction part for liquefying the distilled mobile phase; and

a purification part disposed between the mobile phase distillation part and the mobile phase liquefaction part,

wherein the purification part comprises:

a cellulose or silica thimble for mixing the mobile phase liquefied at the mobile phase liquefaction part with to-be-purified material;

a bonded phase for removing impurities from the mixture; and

a soxhlet for sending purified material, in which the impurities are removed by the bonded phase, to the mobile phase distillation part.

2. The purification apparatus of claim 1 , wherein the mobile phase distillation part comprises:

a flask containing the mobile phase therein; and

a heater for generating heat so as to distill the mobile phase.

3. The purification apparatus of claim 2 , wherein the mobile phase is an organic solvent.

4. The purification apparatus of claim 1 , wherein the mobile phase liquefaction part is a reflux condenser.

5. The purification apparatus of claim 1 , wherein the bonded phase is at least one selected from the group consisting of silica gel, alumina, celite and activated carbon.

6. The purification apparatus of claim 1 , wherein the bonded phase further comprises a predetermined thickness of a sand layer formed on upper and lower surfaces thereof.

7. The purification apparatus of claim 1 , wherein the soxhlet sends the impurity-removed purified material to the mobile phase distillation part through a capillary tube.

8. The purification apparatus of claim 7 , wherein an inlet of the capillary tube is filled with cotton such that only the purified material passes.

9. A purification apparatus comprising:

a flask for containing an organic solvent therein;

a heater for distilling the organic solvent;

a condenser for liquefying the distilled organic solvent;

a cellulose or silica thimble disposed at a lower portion of the condenser, for mixing the organic solvent liquefied at the mobile phase liquefaction part with to-be-purified organic material;

a bonded phase disposed at a lower portion of the cellulose or silica thimble, for removing impurities from the mixture; and

a soxhlet for sending the purified material, in which the impurities are removed by the bonded phase, to the flask.

10. The purification apparatus of claim 9 , wherein the condenser is a reflux, condenser.

11. The purification apparatus of claim 9 , wherein the bonded phase is at least one selected from the group consisting of silica gel, alumina, celite and activated carbon.

12. The purification apparatus of claim 9 , wherein the bonded phase further comprises a predetermined thickness of a sand layer formed on upper and lower surfaces thereof.

13. The purification apparatus of claim 9 , wherein the soxhlet sends the impurity-removed purified material to the flask through a capillary tube.

14. The purification apparatus of claim 13 , wherein an inlet of the capillary tube is filled with cotton such that only the purified material passes.

15. A purification method using a purification apparatus having a mobile phase distillation part; a mobile phase liquefaction part and a purification part disposed between the mobile phase distillation part and the mobile phase liquefaction part, for removing impurities of to-be-purified material, the method comprising the steps of:

distilling a mobile-phase solvent;

liquefying the distilled solvent;

mixing the liquefied solvent with the to-be-purified material using a cellulose or silica thimble;

removing impurities from the mixture using a bonded phase;

using a soxhlet to send the purified material, in which the impurities are removed by the bonded phase, to the mobile phase distillation part; and

extracting the purified material from the mobile phase distillation part.

16. The purification method of claim 15 , wherein the bonded phase is at least one selected from the group consisting of silica gel, alumina, celite and activated carbon.

17. The purification method of claim 15 , wherein the purified material is moved to the mobile phase distillation part by a capillary phenomenon having a difference of a surface tension.

18. The purification method of claim 15 , wherein the purified material is purified by a polarity difference of the mixture.
