What Does HCL Stand For?
HCL stands for Hollow Cathode Lamp
Hollow Cathode Lamp (HCL) is a type of light source commonly used in atomic spectroscopy. It consists of a hollow cathode made from the element of interest, which emits light when an electric current is applied. The emitted light is monochromatic and highly characteristic of the specific element, making HCLs essential for quantitative analysis in various applications, including environmental monitoring, biomedical research, and industrial testing. Their high intensity and narrow spectral lines enhance sensitivity and precision in analytical methods such as atomic absorption spectroscopy (AAS).
