Abstract: The present invention provides a device capable of conducting magnetic solid-phase extraction, including a framework assembly. The framework assembly includes a platform assembly and an electrical cabinet assembly. The electrical cabinet assembly is disposed below the platform assembly, and an electric assembly is packaged in an electrical cabinet of the electrical cabinet assembly. The electric assembly is disposed independent from the platform assembly. Data wires connected to the electric assembly and the platform assembly are placed in the framework frame or a sheet metal structure, preventing reagents and operations on the platform assembly from polluting or affecting the electric assembly. The present invention designs a magnetic solid-phase extraction device. Pretreating samples in a manner of magnetic solid-phase extraction simplifies the extraction process, reduces the processing costs of the device, and overcomes negative effects caused by some other extraction methods in the background.

Abstract: A full-automatic sample pretreatment device includes a frame module, a cap removing module, a blood-collection tube grasping module, a pipette module, a platform module, a handling module, a film sealing module, a magnetic solid phase extraction module, an SPE positive pressure extraction module and a conveyor belt waste transfer module. A conveyor belt waste transfer module is arranged at a bottom of the frame module, the cap removing module, the platform module and the magnetic solid phase extraction module are sequentially arranged in the middle of the frame module from left to right, and the blood-collection tube grasping module, the pipette module, the handling module and the film sealing module are arranged at an upper portion of the frame module. The magnetic solid phase extraction module and the SPE positive pressure extraction module are detachable and interchangeable components.

Abstract: The present invention relates to a mass spectrometry device containing an ion transport channel. The ion transport channel is a gradual ion transport channel, an inner diameter of the ion transport channel is gradually reduced, the strength of an electric field formed in the channel is gradually enhanced, and an area of an effective electric field is gradually reduced. Such a device allows ions to be transported stably in the transport channel and increasingly aggregated, thereby reducing the loss of ions, improving the sensitivity and resolution of later detection, and reducing the cost of the device.
