流动注射分析是一种快速的连续流动分析方法。1977年我单位方肇伦等用流动注射法测定了土壤全磷。我们又进一步把流动注射法应用于土壤速效磷的测定,试制了一种电磁进样阀,达到120样/小时的测定速度。与手工操作法相比,分析的精密度与灵敏度都是满意的。实验部分 (一)仪器设备实验中利用了意大利Carlo Erba
Flow injection analysis is a fast, continuous flow analysis method. In 1977 my unit Fang Zhaolun and other flow injection determination of total phosphorus in soil. We further applied the flow injection method to the determination of available phosphorus in soil and developed an electromagnetic injection valve to achieve the measurement speed of 120 samples per hour. Compared with the manual method, the analysis of the precision and sensitivity are satisfied. Experimental part (a) equipment used in the experiment Italy Carlo Erba
