A strategy for electrochemical detection (ED), based on digital integration of the current response at a Au electrode resulting from a square potential–time waveform, is applied for the direct detection of organic polyamines in complex samples foll

Results are described from research designed to optimize the potential–time (E–t) waveform applied in integrated square-wave detection (ISWD). More specifically, goals of this study included the minimization of background signal with maximization

Pulsed amperometric detection (PAD), integrated voltammetric detection (IVD), and integrated square-wave detection (ISWD) at gold electrodes are compared for the flow injection detection of 1,3-diaminopropane in a liquid chromatograph (LC). These det

Pulsed electrochemical detection (PED) is applied at Au electrodes for the determination of aliphatic amines in alkaline media. Here, this detection system is demonstrated for aliphatic monoamines separated from acidic media using a high-capacity cat
