Differential pulse anodic stripping voltammetry (DPASV) coupled with redox-
magnetohydrodynamics (MHD) is used to enhance the anodic stripping voltammetry (ASV)
response using a mercury thin film–glassy carbon electrode. The sensitivity increased to at
least a factor of two (at 1.2 T) and is facilitated by using 20.0 mmol LÀ1 1, 4-benzoquinone
as an alternative pumping species to enhance ASV by redox-MHD. The MHD force formed
by the cross-product of ion flux with magnetic field induces solution convection during the ...
