专利汇可以提供Measuring instrument using bio-sensor专利检索,专利查询,专利分析的服务。并且PURPOSE:To make it possible to easily measure even a small amount of a sample, by providing a bio-sensor to a liquid inhalator. CONSTITUTION:A liquid inhalator is constituted of a cylinder 8, a piston 9 and a needle 10 while an enzyme electrod 11 formed by allowing an electrode plate 11b to immobilize an enzyme film 11a and an opposed electrode 12 are fixed to the inner wall side of the leading end of the cylinder 8 in the side of the needle 10. A potentiostat 6 is connected to the enzyme electrode 11 and the opposed electrode 12 and both electrodes 11, 12 constitute an enzyme sensor. In measuring the concn. of a substrate solution by usng this measuring instrument, the leading end part of the needle 10 is at first immersed in the substrate solution and the piston 9 is withdrawn to such the substrate solution into the cylinder 8. In the next step, voltage is applied between the enzyme electrode 11 and the opposed electrode 12 by the potentiostat 6 and the current value flowing between both electrodes. Thus obtained current value corresponds to the concn. of the basic solution.,下面是Measuring instrument using bio-sensor专利的具体信息内容。
