PURPOSE:To attain 10 simplify measuring operation, by solubilizing a hardly water-soluble lipid specimen by using a surfactant in order to prepare a specimen. CONSTITUTION:The enzyme sensor 2 of a measuring apparatus is constituted of a lead wire 1, an epoxy resin 2, a reference electrode 3, pH-ISFET4, a lipase immobilized membrane 5 and a substrate 6. For example, when a lipid specimen 8 using polyoxyethylene glycol P-t-octylphenyl ether as a surfactant reaches a sensor 12 through a tube 15, lipase in the lipase immobilized membrane 5 decomposes lipid. Next, fatty acid generated as the result of this reaction is monitored by pH-ISFET4 and signal processing is performed by a measuring circuit 13 to record a measured value on a recorder 14. By this method, the preparation of a specimen and lipid measuring operation can be simplified. |
