Multi Micro-Hollow Cathode Light Source and Multi-Atomic Simulataneous Absorption Spectrum Analyzer

Abstract

[Object] To achieve a compact point light source exhibiting multielement emission spectra with which multi elements can be simultaneously analyzed. [Solving Means] The light source includes a glass vessel 40 containing He gas; a plurality of micro hollow pipes 11 that are cylindrical with a diameter of 1 mm or less and made of copper or a copper alloy; an anode mesh 32 provided at ends of the micro hollow pipes 11 with an insulating spacer 33 between the anode mesh 32 and the ends; a metal wire 14 provided in the micro hollow pipe 11, the metal wire being made of an element corresponding to a desired light-source spectrum.
