摘要： A gas sensor, including a cylindrical outer tube; and a seal member disposed therein, the seal member including: a lead wire insert hole and an atmosphere communication hole. The seal member has a groove extending outwards in a radial direction at a rear end-facing surface from the atmosphere communication hole while circumventing the lead wire insert hole, the groove having a cutout toward the front end of the seal member. The gas sensor further includes: a protection portion which covers the atmosphere communication hole; and an arm couples the protection portion and the outer tube, and extends in the radial direction, the arm being at least partially disposed in the groove of the seal member. and the arm is disposed so as to define a gap with the bottom surface of the groove.

摘要： A method of making an electrophoresis medium having a predetermined gradient in concentrations of an acrylamide compound and a cross-linking agent comprises the steps of mixing two kinds of aqueous solutions containing the acrylamide compound and the cross-linking agent in different concentrations such that a mixing ratio of the aqueous solutions to each other is changed gradually, thereby to form a predetermined gradual change (gradient) in concentrations of the acrylamide compound and the cross-linking agent in the mixture, and carrying out cross-linking polymerization of the mixture in the presence of a polymerization initiator. Viscosity values of the two kinds of the aqueous solutions containing the acrylamide compound and the cross-linking agent in different concentrations prior to the mixing are adjusted to be substantially equal to each other.

摘要： An electrophoresis medium membrane comprises a planar support, a planar cover sheet, and a layer of an electrophoresis gel medium provided between the planar support and the planar cover sheet. The electrophoresis gel medium contains an aqueous polyacrylamide gel, which is prepared by cross-linking polymerization of an acrylamide compound and a cross-linking agent in the presence of water and a compound having at least one carbamoyl group as a denaturing agent (or modifier). The layer of the electrophoresis gel medium has both a predetermined gradual change (gradient) in layer thickness and a predetermined gradual change (gradient) in concentrations of the acrylamide compound and the cross-linking agent.
