[0002] The hollow cathode lamp is a special glow discharge tube that is widely used in atomic absorption spectrometry. It consists of a hollow cylindrical cathode and an anode. The cathode is hollow cylindrical and made of pure metal or alloy of the element to be measured. When an appropriate voltage is applied between the two poles, electrons are ejected from the cathode to the anode. In the process, they collide with the surrounding inert gas atoms, causing them to be ionized. The generated positive ions are accelerated by the electric field to bombard the cathode surface, causing the atoms on the cathode surface to sputter out and collide with electrons, inert gas atoms and ions to be excited, emitting characteristic spectral lines of the element to be measured. The hollow cathode lamp has the advantages of narrow emission spectrum, high intensity and good stability.
