Urea-sensitive sensors, based on immobilized urease and the differential antimony electrode, have been constructed. The calibration curve of the sensor is linear up to 1.6-2.0 mmol litre-1 in the stationary or kinetic mode of operation. The sensors retain 50% of their sensitivity for 16-17 days. The analyser for urea, constructed on the basis of the sensor, ensures quick and precise urea determination in pure blood.
基于固定化脲酶和差分锑电极构建了尿素敏感传感器。在静态或动态操作模式下，该传感器的校准曲线在高达1.6 - 2.0毫摩尔/升的范围内呈线性。这些传感器在16 - 17天内保持其灵敏度的50%。基于该传感器构建的尿素分析仪可确保在纯血中快速、精确地测定尿素。
