Abstract

PURPOSE:To easily obtain a small-sized ring with a gas permeable membrane by preparing the ring with the gas permeable membrane by thermal welding of a film consisting of FEP and tube in order to form the gas permeable membrane as prefabricated parts. CONSTITUTION:The inside and outside diameters of the tube 1 are decided to comply with the size of the gas sensor to be used for a biosensor. The film 2 consisting of an ethylene fluoride/propylene fluoride copolymer resin FRP is applied on the tube 1having a flattened top end and is pressed to a hot plate 3 subjected to a surface treatment by dimethylchlorosilane, by which the tube and the film are thermally welded. The temp. of the hot plate 3 is controlled to 250-260 deg.C and the shape thereof is provided with a hole 4 sized to the inside diameter of the tube 1. The tube 1 is finally cut to a prescribed thickness, by which the ring 5 with the gas permeable membrane is completed.

゛ The present invention relates to a gas sensor and a method of manufacturing a gas permeable membrane for a biosenna using the same. There is a demand for miniaturization of biosensors, and gas sensors must also be miniaturized. As parts become smaller as a result, structures and manufacturing methods that are easy to assemble even when the size becomes smaller are required.
