In an analyzer that directly connects a liquid chromatograph and a mass spectrometer, a mobile phase liquid for an analysis sample and a sample liquid for mass spectrometer calibration are connected via a three-way valve, and either one of the It is sent out by a liquid pump, after the liquid pump, and before the sample injector and analytical column.
A 3-way valve with a drain function is provided, and one end of the output of the 3-way valve is used as an analysis flow path passing through the sample injector and the analytical column, and the other end is used as a drain flow path, and the analysis flow path is usually connected to a mass spectrometer. By switching the flow path connected to the mass spectrometer, it is possible to send the calibration sample solution for the mass spectrometer to the mass spectrometer without passing through the syringe or analytical column using a single liquid pump. A sample introduction device characterized by: 2. In the sample introduction device according to claim 1,
A sample introduction device characterized by automatically switching between a mobile phase liquid for analytical samples and a mass spectrometer calibration sample liquid.
