Abstract

According to one embodiment, a sample preparation cartridge includes, in a container, a first capture unit which captures an inclusion, a second capture unit provided spaced apart from the first capture unit, which captures a contaminant, a first space provided on one surface side of the first capture unit, a second space provided on one surface side of the second capture unit, and an inflow channel on the other surface side of the second capture unit, the second space is provided in parallel with the first space, and the first space and the second space are communicated to a third space between the first capture unit and the second capture unit.

Claims (46)

1 . A sample preparation cartridge comprising, in a container:

a first capture unit which captures an inclusion;

a second capture unit disposed to be spaced apart from the first capture unit, which captures a contaminant;

a first space provided on one surface side of the first capture unit;

a second space provided on one surface side of the second capture unit;

a third space provided between the first capture unit and the second capture unit; and

an inflow channel provided on an other side of the second capture unit,

the second space being provided in parallel with the first space and communicated to a third space.

2 . The sample preparation cartridge of claim 1 , wherein

the first capture unit is a solid-phase extractant.

3 . A sample preparation cartridge comprising, in a container:

a second capture unit that captures an inclusion;

a first capture unit that captures a contaminant;

a first space provided on one surface side of the first capture unit;

a second space provided on one surface side of the second capture unit;

a third space provided between the first capture unit and the second capture unit; and

an outflow channel provided on an other side of the second capture unit,

the second space being provided in parallel with the first space and communicated to the third space.

4 . The sample preparation cartridge of claim 3 , wherein

the second capture unit is a solid-phase extractant.

5 . The sample preparation cartridge of claim 2 , wherein

a sample is passed through the solid-phase extractant, the inclusion is captured by the solid-phase extractant, and a remainder of the sample that passes through the solid-phase extractant is dispensed into an analysis unit of an automatic analyzer.

6 . The sample preparation cartridge of claim 4 , wherein

a sample is passed through the solid-phase extractant, the inclusion is captured by the solid-phase extractant, and a remainder of the sample that passes through the solid-phase extractant is dispensed into an analysis unit of an automatic analyzer.

7 . The sample preparation cartridge of claim 2 , wherein

a sample is passed through the solid-phase extractant, the inclusion is captured by the solid-phase extractant, and a remainder of the sample that passes through the solid-phase extractant is dispensed into an analysis unit of an automatic analyzer, and

further a liquid that can elute the inclusion is passed through the solid-phase extractant in which the inclusion is captured, an eluate in which the component captured by the solid-phase extractant is eluted is extracted, and the eluate is dispensed into the analysis unit of the automatic analyzer.

8 . The sample preparation cartridge of claim 4 , wherein

a sample is passed through the solid-phase extractant, the inclusion is captured by the solid-phase extractant, and a remainder of the sample that passes through the solid-phase extractant is dispensed into an analysis unit of an automatic analyzer, and

further a liquid that can elute the inclusion is passed through the solid-phase extractant in which the inclusion is captured, an eluate in which the component captured by the solid-phase extractant is eluted is extracted, and the eluate is dispensed into the analysis unit of the automatic analyzer.

9 . An automatic analyzer for analysis using the sample preparation cartridge of claim 1 , the analyzer comprising:

an analysis unit,

the analysis unit further comprising:

a mass spectrometer and a sample preparation area,

the sample preparation area comprising:

a sample supply unit, a reaction tank, a reagent storage unit, a sample preparation cartridge supply unit, a sample preparation cartridge installation mechanism and a disposal unit,

the sample preparation cartridge supply unit including a mechanism which transfers the sample preparation cartridge and a sample suction mechanism which transfers a sample in the reaction tank to the sample preparation cartridge, and

the sample preparation cartridge installation mechanism moves the sample preparation cartridge to the mass spectrometer or the disposal unit.

10 . An automatic analyzer for analysis using the sample preparation cartridge of claim 2 , the analyzer comprising:

an analysis unit,

the analysis unit further comprising:

a mass spectrometer and a sample preparation area,

the sample preparation area comprising:

a sample supply unit, a reaction tank, a reagent storage unit, a sample preparation cartridge supply unit, a sample preparation cartridge installation mechanism and a disposal unit,

the sample preparation cartridge supply unit including a mechanism which transfers the sample preparation cartridge and a sample suction mechanism which transfers a sample in the reaction tank to the sample preparation cartridge, and

the sample preparation cartridge installation mechanism moves the sample preparation cartridge to the mass spectrometer or the disposal unit.
