“…Capacitively coupled contactless conductivity detection (C 4 D) has been used extensively as a detector in separation science. 24,25 In addition, the C 4 D cell has found alternate use as a characterisation tool of stationary phases for capillary columns, 26 separation channels in microfluidic devices, 27 flow measurements, 28 and a recent electrical sensor for the simultaneous amplification and detection of specific sequence DNA. 29 The true benefit of this form of detection is related to its non-destructive character, providing characteristic information regarding the cell contents without disturbing the system under observation.…”

The use of capacitively coupled contactless conductivity detection (C 4 D) for the characterisation of thin conductive graphene fi bres, graphene composite fi bres, and graphene coated fi brous materials is demonstrated for the fi rst time. Within a few seconds, the non-destructive C 4 D detector provides a pro fi le of the longetudinal physical homogeneity of the fi bre, as well as extra information regarding fi bre mophology and composition. In addition to the theoretical considerations related to the factors a ff ect the output signal, this work evaluates the properties of graphene fi bres using scanning C 4 D following the manufac-turing process of wet-spinning. Furthermore, conductive graphene-coated fi brous materials and the e ff ectiveness of the coating and reduction procedures applied could be investigated. Apart from the application of C 4 D in the monitoring of such processes, the feasibility of this small, highly sensitive and rapidly-responsive detector to monitor strain and elasticity responses of conductive and elastomeric composite fi bres for applications in motion sensing, biomedical monitoring, and stretchable electronics was also demonstrated.Keywords graphene, fibres, coated, capacitively, coupled, contactless, conductivity, detector, characterisation Disciplines Engineering | Physical Sciences and Mathematics Publication DetailsCabot, J.

This chapter presents a fundamental overview over current detection systems used in capillary electrophoresis with the focus on modern trends. Attention is paid mainly to UV ‐ Vis absorption spectrometric, fluorescence, amperometric, contactless conductivity, and electrochemiluminiscence detectors. Each detection technique is characterized by fundamental physical–chemical principle, designs of detection cells, and examples of typical applications are presented. Special attention is given to combinations of detection techniques used in multidimensional detection systems.
