Sample preprocessor and analysis system

Abstract

The purpose of the invention is to provide a sample preprocessor (100) that can obtain a precise amount of sample liquid after filtering and enhance the accuracy of subsequent measurement, and the like. The sample preprocessor (100), filters a sample liquid so as to capture a prescribed component with a filter (F), and comprises a connection mechanism (2) for connecting a suction source and a sample container (S) comprising a bottle (S1) for storing the sample liquid and a cylindrical cartridge (S2) that has a proximal side connected to the bottle (S1) and has the filter (F) provided therein.The connection mechanism (2) comprises a suction terminal (22) that connects the distal side of the cartridge (S2) and the suction source and sucks in the sample liquid that is inside the sample container (S), and an attachment surface (26) that the bottle (S1) is attached to and positions the cartridge (S2) in a prescribed position in relation to the suction terminal (22).

Description

technical field [0001] The present invention relates to a sample preprocessing machine for filtering a sample liquid to filter out a predetermined component in the filter. Background technique [0002] When measuring, for example, the amount of ATP and / or the amount of microorganisms present, the sample liquid is filtered with a filter to increase the concentration of a predetermined component in the sample liquid. [0003] In such pretreatment, a sample container having a filter inside and storing a sample liquid is used, and a sample container connected to the sample container is used to suction the sample liquid in the sample container through the filter to be filtered. Sample pretreatment machine. The sample liquid in the sample container is concentrated by this filtration. [0004] However, in such measurement for the purpose of ATP and / or microorganism detection, even a small error in the amount of the sample liquid may cause a large measurement error. [0005] In a...

Problems solved by technology

[0004] However, in such a measurement for the purpose of ATP and / or microorganism detection, even if the error in the amount of the sample liquid is small, a large measurement error may occur.

[0005] In addition, since a sample container containing a different sample solution is connected to the suction terminal for each filtration, there is a possibility that ATP and / or microorganisms attached to the suction terminal during the previous filtration may contaminate the currently installed sample container.
