The invention discloses a multifunctional horizontal natural gas separation filter belonging to the technical field of filter devices. The multifunctional horizontal natural gas separation filter comprises a cylinder, a blind plate and a blind plate locking mechanism, and is characterized in that latch plate sliding cavities are formed in one side, back on to a separation filter cavity, of the blind plate; the blind plate locking mechanism comprises latch plates, a center disk shaft, a center disk, a traction plate and a center disk operation handle; a center disk sleeve is fixed on one side, back on to the blind plate, of the center disk and is perpendicular to the center disk; a cylinder depressurizing response mechanism is arranged on the wall body of one side, back on to the separation filter cavity, of the blind plate, and is matched with the center disk; a clean hole is formed in the circumferential direction of a blind plate matching opening and in the position corresponding to a blind plate locking groove; a sealing screw is arranged on the clean hole in a matching manner. The multifunctional horizontal natural gas separation filter has the advantages that the structure is simple; the ideal effect of latching all the latch plates and the blind plate locking groove can be enduringly kept; the blind plate is prevented from being deformed; when natural gas exists in the cylinder, the blind plate cannot be opened; the blind plate locking groove can be quickly and conveniently cleaned.

A method is disclosed for concentrating sample constituents and for multiplying nucleic acids from a biological sample which are containing in the sample constituents. The nucleic acids are amplified on the same filter on which the sample constituents are also separated off.
