MULTI-MICRO HOLLOW CATHODE LIGHT SOURCE AND MULTI-ELEMENT SIMULTANEOUS ABSORPTION SPECTROMETRY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a small-size point light source having multi-element emission spectrum in which multi-elements can be analyzed simultaneously.;SOLUTION: The point light source has He gas filled into a glass container 40 and comprises a plurality of tubular micro hollow pipes 11 made of copper or copper alloy with a diameter of 1 mm or less, an anode mesh 32 arranged at the tip of these micro hollow pipes 11 through an insulating spacer 33, and a metallic wire 14 which is installed inside the micro hollow pipes 11 and is made of an element corresponding to the light source spectrum to be obtained.;COPYRIGHT: (C)2008,JPO&INPIT
