Abstract
A flow injection gas diffusion system for ps acceptor to liquid donor stream, reverse dual phase ps diffusion flow injection analysis, has b een demonstrated. Feasibility was shown with a carbon dioxide chemistr y. A series of methods was investigated for hydrazine determinations. Using bromthymol blue indicator and a Celgard 2500 membrane a detectio n limit of 0.01 ppm v/v hydrazine was observed.
