Abstract

This paper presents design, fabrication and evaluation of a polydimethylsiloxane (PDMS) —glass microfluidic device for quantitative determination of manganese ion (Mn(II)) in oceanic environments. The microfluidic device can perform luminol-hydrogen peroxide chemiluminescence (CL) reaction in a flow-through manner for highly sensitive Mn (II) quantification. A chelate resin column was integrated in the microfluidic device for removal of coexisting metal ion such as Fe(II). The developed device could quantify Mn(II) in nM level under coexistence of μM level of Fe(II). The microfluidic device developed here will be used as a core element of a totally integrated in situ chemical analyzer that we have been developing for oceanography applications.
