Measuring device for liquid sample and method for measuring liquid sample

摘要

An objective of this invention is to achieve good measurement accuracy, stable measurement sensitivity and rapid response in a device for measuring a liquid sample and a method for measuring a liquid sample using a sensor comprising an enzyme layer and to minimize sensitivity reduction in repeated or continuous measurement. A device for measuring a liquid sample consists of a sensor comprising an enzyme layer, an upper case 3 and a lower case 4 sandwiching the sensor 5. The sensor 5 is removable from the upper case 3. The upper case 3 comprises a liquid sample inlet channel 1 and a liquid sample outlet channel 2. The liquid sample inlet channel 1 is placed at an angle to the surface of the sensor 5 while its opening end is placed in the vicinity of the surface of the sensor 5.
