PROBLEM TO BE SOLVED: To eliminate the risk of dropping a filter assembly inside an apparatus chamber, improve workability and simplify operability by forming a sample unit as the filter assembly for collecting fine particles into a cassette. SOLUTION: The fine particle introducing apparatus for introducing fine particles to a plasma-generating part of an element analyzer utilizing microwave induction plasma has a cassette-setting means K for setting, for example, cassettes S1-S4 and L1 as sample units and a reference unit. The cassette-setting means K is moved by a cassette-moving means, i.e., a base Be with a rotation- assisting means R and a cassette position-fixing mechanism L0 to a predetermined position in an apparatus chamber in a Q direction. The moved cassette- setting means K is fitted with a cassette-rotating means TU and rotated by a rotary driving arm E, whereby a predetermined cassette is selected. The selected cassette is set to a predetermined position by a sample unit-setting/ resetting means 4'. |
