摘要：

A sensitive continuous metal ion detection system based on the use of PAR-ZnEDTA has been developed and characterized. Sensitivities of the order of 0.1 to 1.0 nmol, which represents a thousand-fold improvement over previously reported systems, were observed for 13 metal ions. The system has been employed in a liquid chromatographic separation study. © 1979, American Chemical Society. All rights reserved.
