| 摘 要： | 为了快速、定量检测肉类食品中瘦肉精含量,采用了一种先进的激光诱导荧光技术进行检测。首先将稀释好的样品滴加在用免疫层析技术制作的试纸卡上,然后使用638nm波长的半导体激光器照射试纸卡,激发出的荧光通过光敏二极管接收,通过采集荧光强度来实现瘦肉精含量的检测。通过实验验证,该检测系统能够快速、定量、精确的检测瘦肉精的含量,检测时间为6s,测量量程为0.0~0.3ppb,检测灵敏度为0.01ppb。

| Abstract: | In order to detect concentration of clenbuterol fast and quantitatively in meat food,we adopt an advanced laser induced fluores-cence technique.First,a diluted sample is dropped on the reagent card made by immunochromatographic technique.Then we irradiates the reagent card with a 638 nm wavelength laser diode to excite the fluorescence received by the photodiode.Finally,the author collects the fluorescence intensity to achieve the detection of clenbuterol＆#39;s concentration.Experiment shows that the detection system is rapid and quantitative,accurate in detection of concentration of clenbuterol.Detection time is 6,the measurement range is 0.0~0.3 ppb and de-tection sensitivity is 0.01 ppb. |
