![]() ![]() When a high voltage is applied across the cathode and anode, a discharge is initiated within the hollow cathode. The cathode is hollow in shape and is often coated with a layer of the same material to enhance the light intensity. It is typically made of the element or a compound of interest for analysis, such as copper for copper analysis or iron for iron analysis. The cathode is a metal electrode that serves as the source of the emitted radiation in the HCL. These components include the cathode, the anode, the buffer gas, and the lamp envelope. ![]() It consists of several key components that work together to generate the necessary light source for spectroscopic analysis.
