CHI117 is the 25 micron diameter platinum SECM tip, the coarser of the two sizes CH Instruments list. Like the CHI116 it serves as the scanning probe for the 920D Scanning Electrochemical Microscope (SECM).
CHI115 is a platinum wire counter electrode, published with its own figure on the CH Instruments accessory list. It supplies the counter electrode in cells assembled from the working and reference electrodes in the same range.
The CHI120 is the consumable kit CH Instruments supply for renewing the surface of their solid working electrodes. Its published instruction sheet lists 4 grams of 1.0 micron MicroPolish powder, 4 grams of 0.3 micron powder, 18 grams of 0.05 micron powder, two glass plates for the polishing pads, and three grades of 73 mm diameter disc and pad. The stated routine works down through 1.0, 0.3 and 0.05 micron alumina until the electrode surface is mirror shiny, starting at the 1200 grit Carbimet disc if scratches will not lift.
