【摘要】 基于碘-淀粉法并利用流动注射技术开发了一种能在线快速检测唾液α-淀粉酶的检测仪。该仪器携带方便,操作简单,低成本、低耗能,在58s内即可完成一个样本的唾液α-淀粉酶测试。该仪器可实现自动化操作,精密度高,能较好的监测到应激过程,经人体运动应激实验和考试焦虑应激实验的样本检测试用,可以满足人群实验要求。更多还原

【Abstract】 A monitoring instrument was developed based on iodine-starch reaction and flow injection technique for the on-line rapid determination of salivary α- amylase. By using this instrument, the detection time needed for a sample is only 58 s. The instrument can run automatically with a high precision, low cost and low energy-consumption. The developed instrument was successfully applied to the detection of salivary samples from volunteers recruited for an exercise stress test and an exam anxiety stress test. The stress process can be monitored by this instrument with good reproducibility.更多还原
