PURPOSE:To provide a measuring method using an enzyme electrode excellent in the linearity of a concn. indication value, by adding a means for mixing oxygen gas in a liquid to be measured or a means for segmenting the liquid to be measured by oxygen gas. CONSTITUTION:The blood sucked into a blood sampling tube 22 and the dilution liquid supplied from a dilution liquid container 42 are sent to a mixing tube 24. In this case, oxygen gas is supplied to the dilution liquid from an oxygen bomb 36 and oxygen gas is mixed in an amount enough to glucose reaction in the dilution liquid container 42. The liquid to be measured sufficiently mixed in a mixing coil 26 is supplied to an enzyme electrode 30 where a blood sugar level is measured. As mentioned above, by mixing a sufficient amount of oxygen gas in the dilution liquid or by segmenting the blood diluted with the dilution liquid by oxygen gas, oxygen deficiency is eliminated and effect for washing the contamination of the immobilized enzyme membrane on the enzyme electrode is imparted and the output of a measuring electrode is extremely stabilized with the elapse of time. |
