由固定化脲酶、谷氨酸脱氢酶、谷氨酸氧化酶、葡萄糖氧化酶的复合酶膜组成的双电极系统,可以同时测定尿素氮和葡萄糖的含量,每次进样量为25μl,20s即可测定出尿素氮和葡萄糖的含量。在0~60mg/dl尿素氮、0~500mg/dl葡萄糖范围内具有良好的线性关系。连续测定20次的变异系数分别为1.02%和1.05%。酶膜使用寿命为两星期以上。此仪器可广泛应用于临床检验和体育训练中。
The dual-electrode system consisting of immobilized urease, glutamate dehydrogenase, glutamate oxidase, and glucose oxidase complex enzyme membrane can simultaneously measure the content of urea nitrogen and glucose, and each injection volume is 25μl, 20s You can determine the urea nitrogen and glucose content. In 0 ~ 60mg / dl urea nitrogen, 0 ~ 500mg / dl glucose range has a good linear relationship. The coefficients of variation for 20 consecutive measurements were 1.02% and 1.05%, respectively. Enzyme membrane service life of two weeks or more. This instrument can be widely used in clinical testing and sports training.
