Analyzer

An analyzer comprising:

• a pretreatment device;
• pretreated sample transporting means;
• an ionizer that ionizes a sample and causes the sample to be introduced in a mass spectrometer;
• the mass spectrometer that is capable of performing an analysis and measurement;
• and
• a data processing unit,
• wherein the pretreatment device includes:
• a solid phase extraction cartridge;
• a cartridge holding vessel that holds a solid phase extraction cartridge therein;
• cartridge transporting means that is capable of holding a plurality of storage sections (cartridge holding vessels) and has a continuous-track;
• a whole blood treatment unit that is capable of performing a purifying treatment on whole blood;
• a reagent container that is capable of storing a plurality of reagents;
• a rotating arm that is capable of transporting a reagent from the reagent container to the solid phase extraction cartridge;
• a rotating arm that is capable of transporting a reagent from the reagent container to the whole blood treatment unit;
• a pressure applying unit that is capable of continuously and randomly applying pressure to the insides of the storage sections;
• and
• an extracted solution receiving mechanism that selectively receives a solution extracted from the separating agent stored in the storage sections,
• wherein at least one internal standard is used, and the data processing unit stores correlation data on dependence (sensitivity) of the intensities of signals that indicate mass-to-charge ratios m/z of an analyte substance to be measured and the internal standard with respect to the matrix containing phospholipid with the different concentration, and stores a recovery rate of the analyte substance to be measured for the matrix, and
• wherein the concentrations of the phospholipid and the concentration of the analyte substance to be measured are calculated from the signal intensities of the analyte substance to be measured and the internal standard, the intensities being actually measured by the mass spectrometer.
