Summary:PROBLEM TO BE SOLVED: To reduce the necessary quantity of an analyzing sample. SOLUTION: This device is formed of a glove box 4 having a metal plate 5 in the inner part and optical windows 7, 8 on both side surfaces; a micro- pipetter 3 for dropping an analyzing sample onto the metal plate 5 within the glove box 4; a first condenser lens 12 for converging the laser beam from a laser and introducing it to the analyzing sample on the metal plate within the glove box through the first optical window 7; and a second condenser lens 9 for converging the emission spectra of elements contained in the analyzing sample generated by the emission of the laser beam, and emitting them to a multichannel analyzer 10 through the second optical window 8. The emission spectral intensities of a plurality of elements are simultaneously determined, whereby the density quantitative determination of the elements in the analyzing sample can be performed.
