Enhancing the Concentration Capability of Nonsupported Electrically Driven Liquid-Phase Microextraction through Programmable Flow Using an All-In-One 3D-Printed Optosensor: A Proof of Concept

“…This is consistent with previous findings regarding the improved performance of devices with pentagon cross-sections in flow systems. 40 Although the phase formation and stability of the phases were not radically different across the three cross-sectional geometries assessed, the electrical current levels recorded for the pentagon cross-section were higher than those of the other cross-section shapes in almost the first 200 s of μ-EME, thus signaling the improved mass transfer for the channel with the pentagon geometry ( Figure S5 ).…”

The performance of a large-volume DP injection against low-volume μ-EME using the 3D-TSU in the mimicry of the conventional μ-EME linear configuration reported in the literature was assessed to provide invaluable insight into the potential analytical improvements (e.g., EF) harnessing the 3D-TSU arrangements.…”
