Abstract
The electrochemical cell includes a cell base configured to support both a screen-printed electrode chip and a solid disc electrode, a cell body disposed on the cell base and defining a sample chamber, a cell cover disposed on the cell body, and a rotating rod extending through the cell cover into the sample chamber. The cell body is attachable to the cell base in a first orientation to align with the screen-printed electrode chip and in a second orientation to align with the solid disc electrode. Embodiments enable a universal batch cell, functionality that is equivalent to a rotating disc electrode, and dual functionality as both a batch cell and a flow cell.
Claims21
An electrochemical cell for electrochemical analysis, comprising:
- a cell base comprising a screen-printed electrode chip and a solid disc electrode;
- a cell body defining a sample chamber, wherein the cell body is attachable to the cell base in a first orientation to align a neck region with the screen-printed electrode chip and in a second orientation to align the neck region with the solid disc electrode;
- a cell cover detachably connected to the cell body;
- and
- a rotating rod extending through the cell cover into the sample chamber.
A method for configuring an electrochemical cell, comprising:
- selecting an orientation of a cell body on a cell base, wherein the cell base comprises a screen-printed electrode chip and a solid disc electrode, and wherein the orientation determines whether a neck region of the cell body aligns with the screen-printed electrode chip or the solid disc electrode;
- attaching a detachable cell cover to the cell body, wherein the cell cover supports a rotating rod configured to induce hydrodynamic flow at a surface of a selected electrode;
- and
- performing electrochemical analysis using the selected electrode.
A flow injection analysis system, comprising:
- an electrochemical cell comprising a cell base comprising a screen-printed electrode chip and a solid disc electrode, a cell body disposed on the cell base and defining a sample chamber, and a detachable cell cover disposed on the cell body;
- a rotating rod extending through the cell cover into the sample chamber, the rotating rod comprising a longitudinal channel and a tube disposed coaxially therein for delivering a carrier solution;
- means for transferring rotation from an overhead mechanical stirrer to the rotating rod while permitting the carrier solution to flow through the longitudinal channel.
