Novel magnetic solid phase extracting device

The invention provides a novel magnetic solid phase extracting device which comprises a base, a liquid feeding unit, a liquid suction unit and at least one independent operation unit. Each independent operation unit comprises an electromagnetic rod, a liquid feeding rod, a liquid suction rod, screw rods and sliding rods; the liquid feeding unit is connected with the liquid feeding rods, the liquid suction unit is connected with the liquid suction rods, the independent operation units are fixed on the sliding rods and precisely and vertically move on the sliding rods through the mode that high-precision micromotors rotate the screw rods. The liquid inlet unit is used for feeding liquid to a target extract; the liquid suction unit is used for performing liquid suction on the target extract. The invention further provides a method for performing solid phase extracting through the device. According to the magnetic solid phase extracting device and method, simultaneous, rapid and automatic operation can be achieved, operation is easy and convenient, and the excellent application prospect is achieved.
