Title:
SLIME PREVENTING METHOD FOR FLOW PASSAGE OF BIOSENSOR AND FLOW PASSAGE STRUCTURE USED THEREFOR
Document Type and Number:
Japanese Patent JPH07191014
Kind Code:
A
Abstract:
PURPOSE: To stably secure the measuring accuracy of a biosensor using dissolved oxygen electrodes for a transducer by suppressing the increase of microorganism-derived slime in a transferring flow passage in the biosensor and reducing the exchanging frequency of the material of the transferring flow passage.
CONSTITUTION: A by-pass flow passage 2 or 4 is provided on at least either one of a sample transferring flow passage l and buffer solution transferring flow passage 3 which are connected in parallel with each other to a biosensor 24 and the flow rate of the flow passage 2 or 4 is increased from it corresponding flow passage 1 or 3.
