    摘要: A new interface is interposed between a liquid chromatograph and a mass spectrometer, and it consists of a nebulizer, an evaporator and a cooler. An effluent from the liquid chromatograph is nebulized by the nebulizer. The nebulized effluent is heated by the evaporator, and has only its solvent evaporated. A mixed fluid which consists of the evaporated solvent and the nebulized sample is guided to the cooler, and is cooled therein. At this time, the evaporated solvent is condensed again and is separated from the nebulized sample as a liquid. The nebulized sample left behind is guided to an ion source of the mass spectrometer.

    摘要: A liquid chromatograph comprises an analyzing chip in which a capillary is formed in a substrate and a detector section is disposed downstream of the capillary. The capillary is covered so that an inlet opening end and an outlet opening end of said capillary flow path is opened. A frame member has a sample introduction path, a carrier liquid introduction path and a liquid discharge path. The analyzing chip is movably disposed in the frame member so that the inlet opening end and the outlet opening end of the capillary are selectively in communication with and/or under interruption against said sample introduction path, the carrier liquid introduction path and the liquid discharge path. The liquid chromatograph is very small in size but is easy to handle. Incidentally, there is disclosed also a sample introduction apparatus and method for the chromatograph, and an FET type detector suitable for the chromatograph.

    摘要: An autosampler consists of a needle to draw specimen from a specimen container into a passage therein; a block having a passage that follows the passge in the needle; a suction mechanism for drawing in the specimen by suction through the passages in the needle and the block; a discharge mechanism for discarding the specimen drawn in by the suction mechanism; and a detecting device for detecting air bubble in the specimen, the detecting device being embedded in the block in such a manner as to face the passage in the block. The detecting device detects the air bubbles in the specimen according to changes in physical or chemical properties of the specimen passing through the passage in the block. The discharge mechanism is activated by the detecting device to discharge air-mixed specimen. When even a small amount of air is drawn into the passage from the specimen container, in which only a small amount of specimen is contained, the air specimen can reliably be distinguished from normal specimen by this autosampler. Therefore the reliability of the system using the autosampler can be significantly improved.
