PURPOSE:To establish analytical technique reduced in an analytical error and having reproducibility by providing filter paper eliminating the liquid sump due to surface tension to the upper surface of a tray made of aluminum and dripping a sample to be inspected on the filter paper to develop the same uniformly and widely. CONSTITUTION:The measurement of a non-volatile component is performed according to the program of a computer and a lid is opened by a lid opening and closing mecha nism and a tray 503 is taken out of a tray container by an analytical robot 1 through a suction jig to be set on a balance 506 and subsequently closed. Subsequently, the lid is again opened and a sample to be inspected is dripped on the filter paper 509 on the tray 503 by the analytical robot 1 through a tip 50. The sample to be inspected is dripped from a place separated by a predetermined distance from the surface of the filter paper 509. The dripped liquid droplet 51 of the sample to be inspected forms a liquid sump 52 on the surface of the filter paper 509. Next, when the chip 50 is let fall so as to be brought into contact with said liquid sump 52, the liquid sump 52 penetrates and diffuses into the filter paper 509 and the liquid sump accumulated at the leading end of the chip 50 can also be eliminated. |
