Sample pretreatment apparatus and mass spectrometer provided with the same
View Patent ↗The present invention relates to a pretreatment apparatus that performs concentration and separation of a sample, and in particular, in order to provide a sample pretreatment apparatus using a solid-phase extraction column, and a mass spectrometer using the same, which is particularly suitable for clinical analysis in which qualitative/quantitative analysis of a biological sample such as blood is performed, according to each operational step for a solid-phase extraction treatment, for example, a collection device serving as flow passages or containers for collection of waste liquid or extracted matter is installed on a bottom face of the solid-phase extraction column, and the extracted matter is separately collected without being mixed with waste liquid by switching the positions of the collection device.
1. A biological sample pretreatment apparatus comprising:
a cartridge capable of holding a extraction agent for solid-phase extraction;
a solid-phase extraction cartridge holding unit capable of holding a plurality of the cartridges; and
a tray mechanism that receives a sample extracted from the cartridge, wherein
the tray mechanism is composed of a plurality of receiving sections, and a section switching mechanism that switches the receiving sections to receive the sample extracted from the cartridge is provided.
2. The biological sample pretreatment apparatus according to claim 1 , wherein
the section switching mechanism is a mechanism that switches flow passages.
3. The biological sample pretreatment apparatus according to claim 2 , wherein
the mechanism that switches flow passages is a valve mechanism installed in the solution discharge port that receives the sample extracted from the cartridge.
4. The biological sample pretreatment apparatus according to claim 3 , wherein
the valve mechanism is installed in another part of an apparatus main body.
5. The biological sample pretreatment apparatus according to claim 1 , wherein
the section switching mechanism is a mechanism that moves a tray.
6. The biological sample pretreatment apparatus according to claim 5 , wherein
the mechanism that moves a tray is a mechanism that rotates a tray.
7. The biological sample pretreatment apparatus according to claim 6 , wherein
a solution discharge port that receives the sample extracted from the cartridge is deviated from a center of a bottom face of the cartridge.
8. The biological sample pretreatment apparatus according to claim 5 , wherein
the mechanism that moves a tray is a mechanism that slides a tray.
9. The biological sample pretreatment apparatus according to claim 1 , wherein
the tray mechanism and the cartridge are integrated with each other.
10. The biological sample pretreatment apparatus according to claim 9 , comprising
a pressure relief mechanism that relieves pressure in the cartridge capable of holding the extraction agent for solid-phase extraction.
11. The biological sample pretreatment apparatus according to claim 1 , wherein
the section switching mechanism is installed in another part in an apparatus main body.
12. The biological sample pretreatment apparatus according to claim 1 , comprising:
a plurality of said cartridges and a plurality of said tray mechanisms; and
a collection target switching mechanism that switches the receiving sections for at least two of the cartridges for use between waste liquid collection and extracted sample collection independently.
13. A mass spectrometer comprising the biological sample pretreatment apparatus according to claim 12 .
