ESA / Model 5020 / Guard Cell is specialized in its design, employing the patented ESA flow-through porous graphite electrode. These low-volume analytical cells contain two working electrodes. The high surface area of each electrode results in 100% reaction of the electroactive compound. The first (screening) electrode can be used to eliminate potentially interfering compounds from subsequent detection at the second (analytical) electrode. This model is designed to withstand high pressures. It has a single large porous graphite electrode which removes electroactive impurities from the mobile phase prior to the injector, column and analytical cell. This decreases background currents and reduces baseline noise.
