摘要：

A programmable propulsion system which allows the establishment of flow-rate gradients in unsegmented flow systems was developed. The flow gradients can be applied as such or used to create other types of gradients in flow configurations, with or without sample injection. Reproducible concentration gradients were obtained and used to calculate the stoichiometries of metal complexes and to determine acidity constants. © 1990.
