Abstract
Disclosed is a purification apparatus and method. The purification apparatus includes: 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, for mixing the mobile phase liquefied at the mobile liquefaction part with to-be-purified material, removing impurities from the mixture through a bonded phase, and sending the impurity-removed purified material to the mobile phase distillation part.
Claims18
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.
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.
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.
