Abstract: An object of the present invention is to provide a small and compact analytical apparatus. An input/output device for directing the analytical apparatus and displaying analytical results and operation conditions is detachably provided on a body of the apparatus. Since the input/output device can be fixed to an upper position of the body, the apparatus saves space and can be placed on a desk. The analytical apparatus includes a sample disk and a reagent disk. The diameter of the reagent disk is greater than that of the sample disk, and both disks are arranged at the front of the apparatus so that the center of the sample disk is nearer the operator side than the center of the reagent disk. Therefore, the whole arrangement is compact, and the apparatus itself is compact.

Abstract: A casing structure for chromatograph having a plurality of casings respectively installing at least a separating column, a sample inducing portion and/or a detector portion of the chromatograph and the casings are vertically stacked one on another or horizontally juxtaposed one to another. The casing structure further comprises a passage for installing reagent feed pipes therein, and the passage is respectively provided in respective side portions of the casing for communicating with that of another casing when in the stacked state or in the juxtaposed state, and has an inner hole at an inner side thereof for connecting the reagent feed pipes to a pipe connecting portion arranged in the casings, and the passage has a cover at an outer side thereof for being opened outside of the casing.
