Abstract
A flow injection gas diffusion system for gas acceptor to liquid donor stream, reverse dual phase gas diffusion flow injection analysis, has been demonstrated. Feasibility was shown with a carbon dioxide chemistry. A series of methods was investigated for hydrazine determinations. Using bromthymol blue indicator and a Celgard 2500 membrane a detection limit of 0.01 ppm v/v hydrazine was observed.
摘要
一种用于气体受体到液体供体流的流动注射气体扩散系统——反向双相气体扩散流动注射分析已得到证实。以二氧化碳化学为例展示了其可行性。研究了一系列测定肼的方法。使用溴百里酚蓝指示剂和Celgard 2500膜，观察到肼的检测限为0.01 ppm v/v。
