Paper Abstract

The paper discusses the fabrication and the test results of a blood urea nitrogen sensor (BUN) and a chloride sensor. The BUN sensor consists of a potentiometric ammonium ion sensor covered by a polymer membrane that contains the immobilized enzyme urease. The chloride sensor is a liquid membrane type electrode. Both electrodes are batch fabricated. The sensors are part of a multispecies sensor chip. The results of the sensor in aqueous solutions and blood will be given. Good uniformity and reproducibility is obtained. The BUN sensor has a linear range of 1 to 20 mM urea and a coefficient of variation of 3% in normal blood.
