Abstract:
A clinical laboratory apparatus includes a pretreating apparatus having a high separation capability and providing high data reproducibility and reliability and a mass spectrometer is provided which executes fully automatic processing from pretreatment to detection. The pretreating apparatus that includes a cartridge for holding an extraction agent for solid-phase extraction, a pressure-loading unit for applying a pressure load to any cartridge mounted on the solid-phase extraction cartridge-retaining unit, a receiving tray mechanism for receiving a sample extracted from the cartridge, and a liquid-level sensor for detecting liquid levels in the receiving tray as well as in the cartridge, conducts feedback control for the pressure-loading unit to open its pressure release valve upon the liquid-level sensor detecting that the liquid level in the receiving tray mechanism has reached a preset liquid-level position.
Abstract:
An analyzer includes a pretreatment device and a mass spectrometer. The pretreatment device includes a solid phase extraction mechanism. The mass spectrometer performs mass spectrometry on a sample pretreated by the pretreatment device and then subjected to ionization. The analyzer also includes a storage unit that stores data on dependence of signal intensities of the analyte substance to be measured and the internal standard upon the concentration of a substance inhibiting ionization in the sample, and that stores data on a recovery rate. The analyzer also includes a correcting unit that corrects measurement results of the sample and the internal standard on the basis of the data stored in the storage unit.
Abstract:
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.
