Abstract
A method, to perform glow discharge optical emission spectrometry using a glow discharge tube equipped with an electrode having an end section, for producing a sample containing object that is to be disposed so as to be opposed to the end section, comprises: covering one end of a sample holding section having a cylindrical shape and being open at both ends using a covering member; filling a powder sample containing a material to be analyzed into the sample holding section; compressing the powder sample by pressurizing the filled powder sample from the other end to the one end of the sample holding section; and removing the covering member from the sample holding section, thereby producing the sample containing object which includes the sample holding section and the compressed powder sample and from which the compressed powder sample is exposed from the one end.
