Multifunctional pressure filter aid solid phase extraction apparatus was concentrated

The present invention discloses a multifunctional pressure solid phase extraction filter aid and concentrated means, comprising the carriage 5, the support base 1, 4 and extracted staging, gas pipeline, the bottom of the bracket 5 is provided a support base, the support base 1 set extracted frame work 4, the carriage 5 is provided pipeline diverter top plate 10, an upper pipeline diverter tray 10 communicates gas delivery manifold 11, 10 communicates gas transmission pipeline diverter manifold plate 9, 9 are respectively connected to gas delivery manifold vent needle 7, gas needle 6 and the piston 7 with the sealing by the sealing extraction column; gas delivery manifold 113 communicates through the airway pressure regulating valve 2. The present invention is constructed by the working gas pressure filter aid operating state, elastically liftable support frame or help maintain airtightness solid phase extraction column end. To achieve a positive pressure extraction, drainage and air blowing is concentrated multiple functions, improving the ability to batch, lower operating costs, versatility and high efficiency. It can be widely used to purify samples of pesticide residues, heavy metals enriched samples, purification and other parts of a particular group of solid phase extraction, sample enrichment operations.
