Abstract: A biological sample is placed on a sample stage (8). The sample stage (8) includes a tray (82), a heater (83), and a temperature sensor (84). On the tray (82), a placement surface (821) on which a biological sample is placed is formed. The heater (83) heats a surface of the tray (82) on an opposite side to the placement surface (821) side. The temperature sensor (84) is provided on an opposite side of the heater (83) to the tray (82) side. The tray (82) is attachable to and detachable from the heater (83).

Abstract: In a PESI ion source, a solvent supply unit (8) is placed above the liver (101), which is the object of measurement, and by moving a probe (6) up and down such that the tip of the probe (6) passes through the solvent supply unit (8) and is inserted into the liver (101), a sample is captured by the tip of said probe. The solvent supply unit (8) includes a container unit comprising a liquid-blocking upper film body (81) stretched over the bottom surface opening of a cylindrical body (80), and a liquid-blocking lower film body (82) which is stretched out approximately in parallel with the upper film body (81) with a spacer interposed therebetween; the container unit houses a solvent (84). Because the tip of the probe (6) passes through the solvent (84) during the up-and-down movement of the probe (6), sufficient solvent adheres to the sample and when a high voltage is applied to the probe (6), components in the sample are favorably ionized.

Abstract: In a sample injector for a gas chromatograph, the present invention improves the throughput of a GC analysis including the derivation of a target compound and reduces the tedious work of handling a reagent for the derivation. According to the present invention, a derivation reagent R is suctioned into a microsyringe 10, after which a small amount of air and a sample P to be analyzed are successively suctioned so that the reagent, the air and the sample are held in this order, from top to bottom. Then, the needle 11 of the microsyringe 10 is inserted through the septum 3 into the sample-vaporizing chamber 2, and the plunger 12 is pushed halfway through so that only the sample is injected into the sample-vaporizing chamber 2. The sample thus injected is quickly vaporized into a gas sample and introduced into the column 6, where the target compound contained in the gas sample adheres to the inner wall of an inlet section of the column 6.
