![]() 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.Clear signals and low distortion due to special cathode technology.Variety of single- and multi-element coded / non-coded in low and high-current, 37 mm and 50 mm lamps The multilayer Si-DLC films have been deposited on AA6061 aluminum alloy using a mesh hollow cathode plasma-enhanced chemical vapor deposition technique from acetylene and silane precursor gas at.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.A schematic diagram of the Varian Mark VI atomization system. The excited atoms of the inert gas and cathode are used for detection and to measure the spectrum while testing. is most often a hollow cathode lamp, which is an intense narrow line source (other sources. 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. Figure 1 is the schematic diagram of our modula-tion transfer spectroscopy setup for the 399 nm laser frequency stabilization. When Voltage gets passed through the anode, the inert gas gets ionized. 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. ![]() This device has been used in wide variety of areas such as spacecraft electric propulsion. Hollow Cathode Effect was first observed in 1916 by Friedrich Paschen, a German physicist, known for his work on electrical discharges. Thermionic hollow cathode is an indispensable component for the applications which require electrons. Hollow Cathode Lamps working totally depends on the hollow cathode effect. 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.
