WebA hollow cathode lamp is used as a spectral line source for Atomic Absorption (AA) instruments. AAS lamps utilize the hollow cathode effect to generate light at wavelengths for the element of interest. The emission line selected must avoid wavelength overlaps, and have good intensity with low noise. WebThis is a lamp in which the cathode is coated with the analyte metal of interest. Within the lamp, inert filler gas (neon or argon) is ionized by an electric current and these ions are then attracted by the cathode. The inert gas ions bombard the cathode and in so doing excite the metal ions coated on it. today\u0027s fly fisher magazine
