Abstract

The present invention relates to an analytical pretreatment device, comprising a supporting material 1, m inlet ports 3 as fluid injection ports, n outlet ports 4 as fluid outlet port, m×n hollow filament 5 communicating between the inlet ports and the outlet ports, and n filler cartridges 6 connected to the outlet ports (wherein, m is a natural number; and n is a natural number) that provides an analytical pretreatment device allowing easier automation of the analytical pretreatment step for improvement in operational accuracy and saving in labor.

Claims

1. An analytical pretreatment device, comprising a supporting material, m inlet ports as fluid injection ports, n outlet ports as fluid outlet port, m×

n hollow filament communicating between the inlet ports and the outlet ports, and n filler cartridges connected to the outlet ports (wherein, m is a natural number; and

n is a natural number).

2. The analytical pretreatment device according to claim 1, wherein at least part of the inlet ports are connected to the supporting material.

3. The analytical pretreatment device according to claim 12, wherein at least part of the outlet ports are connected to the supporting material.

4. The analytical pretreatment device according to claim 1, wherein at least part of the hollow filaments are connected to the supporting material.

5. The analytical pretreatment device according to claim 1, wherein the outlet port and the filler cartridge are integrated.

6. The analytical pretreatment device according to claim 1, wherein there are two or more inlet ports.

7. The analytical pretreatment device according to claim 1, wherein there are two or more outlet ports.

8. The analytical pretreatment device according to claim 1, wherein there are two or more inlet ports and two or more outlet ports.

9. The analytical pretreatment device according to claim 6, wherein at least one hollow filament is placed is such a manner that it crosses at least one other hollow filament.

10. The analytical pretreatment device according to claim 1, wherein the supporting material has a fixing layer for holding the hollow filaments.
