GPT 3.5
The main purpose of a hollow cathode lamp (HCL) is to emit a narrow, intense spectral line for use in atomic absorption spectroscopy, atomic fluorescence spectroscopy, and other analytical techniques. HCLs are commonly used as radiation sources for elemental analysis in atomic absorption and emission spectrometry.
The main limitations of HCLs include their relatively high cost, limited availability of certain spectral lines, and susceptibility to high temperatures and pressure fluctuations. Additionally, HCLs require specialized power supplies and may only be able to emit a limited range of spectral lines, which can restrict their utility in certain analytical applications.
