Label the components of the suppressed-ion cation chromatography schematic shown

Question

Label the components of the suppressed-ion cation chromatography schematic shown below. Then match the component with its description. Each component will be used once when labeling the diagram and once when matching to the description.

Contains a stationary phase with negatively charged groups to attract and retain cations.

Anions are allowed to diffuse across it in both directions from regions of high concentration to regions of low concentration.

It contains two electrodes inside of a flow cell.

It is used to remove unwanted electrolyte and reduce the conductivity of the mobile phase.

Options are:

suppressor

cation separator column

conductivity detector

anion exchange membrane

There is also a diagram with the same options for answers, but I can't get the photo up
