Abstract
Apparatus, methods, and systems related to a thin-layer spectroelectrochemistry cell; electrically coupling a second end of a working electrical wire lead, a second end of a counter electrical wire lead, and a second end of a reference electrical wire lead to a potentiostat; introducing a conductive fluid into a cell body in the spectroelectrochemistry cell; introducing a detection species into the cell body; introducing a sample into the cell body; applying a voltage potential across the transparent sample window to drive an electrochemical reaction between the detection species and the sample in the transparent sample window fluid; transmitting electromagnetic radiation into an optical path through the transparent sample window, thereby optically interacting the electromagnetic radiation with the transparent sample window fluid to generate modified electromagnetic radiation; receiving the modified electromagnetic radiation with a detector; and generating an output signal corresponding to a characteristic of the sample.
