Please visit our Product Page for Hollow Cathode Lamp to know more. Various benefits of Hollow Cathode Lamps makes it ideal for usage in AAS. Heraeus’ lamps are also compatible with all major Atomic Absorption Spectrophotometry including: Can be used for almost any AA instrument.This device has been used in wide variety of areas such as spacecraft electric propulsion. Clear signals and low distortion due to special cathode technology Thermionic hollow cathode is an indispensable component for the applications which require electrons.Variety of single- and multi-element coded / non-coded in low and high-current, 37 mm and 50 mm lamps.Low Noise & hence better spectral responseĪs we are into supply of Hollow Cathode Lamps manufactured by Heraeus, some of the benefits of choosing Heraeus made HCLs are,.Better Lifetime compared to other lamps.The excited atoms of the inert gas and cathode are used for detection and to measure the spectrum while testing. Due to creation of plasma from the inert gas, sputtering of atoms from the cathode takes place as inert gas ions get bombarded on the cathode. The glass tube is filled with some type of inert gas such as argon or neon with a pressure of around 5 torr (666 Pascal). When Voltage gets passed through the anode, the inert gas gets ionized. A HCL consists of an anode and a cathode inside of a glass tube. Typical Hollow Cathode Lamp SetupĪn HCL is formed of a Glass Tube that contains an anode, a cathode and inert gas. Apart from HCLs, Hollow Cathode Effect gets used in neon signages as well. Basically Hollow Cathode Effect is electrical conduction at lower voltage.

Hollow Cathode Effect was first observed in 1916 by Friedrich Paschen, a German physicist, known for his work on electrical discharges.

Hollow Cathode Lamps working totally depends on the hollow cathode effect. Download scientific diagram Schematic of hollow cathode from publication: Design Process of the Hollow Cathode Manufactured for Use in Electric Propulsion Systems as Electron Source Hollow. Hollow Cathode Lamps are ideal source of spectral lines that are used for testing in laboratories. The idea of this blog post is to cover working aspect of Hollow Cathode Lamps followed by its various advantages that fulfills Hollow Cathode Lamps’ usage in AAS.
