SAMPLE CASE FOR ANALYSIS

摘要

PROBLEM TO BE SOLVED: To securely eliminate the degree of risk of organic contamination from environment from an analysis sample by allowing the top flat surface of a dish-shaped body for accepting the analysis sample and aluminum foil for covering a cover chip to adhere to the outer surface of the dish-shaped body. SOLUTION: A recess 13 surrounded by a side wall 12 of a dish-shaped body 10 is at a depth where the upper surface is nearly as high as an upper surface 14 of the side wall top part of the dish-shaped body 10 when two overlapped chips are loaded. The sample case consists of the dish-shaped body 10, aluminum foil 21 for covering the upper surface 14 and the side surface, and a rubber ring 22 for clamping it to the side surface of the dish-shaped body 10. In this case, a sample chip 19 is placed in the recess 13 while a surface to be analyzed of the sample chip 19 faces upward and a cover chip 20 is overlapped. Further, the circular aluminum foil 21 is overlapped onto the dish-shaped body 10 while both centers nearly match. Then, a rubber ring 22 is fixed to a groove 15 at the outer periphery of the dish-shaped body 10, the aluminum foil 21 is clamped to the outer periphery of the dish-shaped body 10, and the overlapping chips 19 and 20 are accommodated airtightly between the aluminum foil 21 and the dish-shaped body 10.
