间隔流动注射分析仪(Segmented Flow injection Analyzer,SFA)是一种微量溶液自动分析技术,其原理是采用连续流动的方法通过蠕动泵压缩不同内径的弹性泵管,将试剂和试样按比例吸入管路系统中并在一定条件下混匀、分离干扰物,保温、反应,显色后测吸光度,计算机处理分析结果。该技术简化了检测人员的检测强度,并能达到令人满意的效果。近年来在水质的监测分析[1]中广泛应用。
Segmented flow injection analyzer (Segmented Flow Injection Analyzer, SFA) is a micro-solution of automatic analysis technology, the principle is the use of continuous flow method by peristaltic pump compression of different diameter elastic pump tube, the reagent and sample proportional suction tube Road system and under certain conditions, mixing, separation of interference, insulation, reaction, color after measured absorbance, computer analysis of the results. This technology simplifies the detection of inspectors and achieves satisfactory results. In recent years, monitoring and analysis of water quality [1] widely used.
