Abstract
PURPOSE:To make a highly sensitive and bright spectroscopic analysis possible, by conveying sample vapor corresponding to a composition component by laser light irradiation, without diluting and diffusing said vapor by carrier gas passing through a flow-rate control part and forming a plasma flame. CONSTITUTION:The sample vapor corresponding to a composition component is generated from a very small area part of a sample 6 in accordance with laser light irradiation. This vapor is conveyed in a small diameter torch 10 penertrating a waveguide 13 without diluting and diffusing said vapor through carrier gas sent from a gas supply part 10 controlling flow rate by a gas flow-rate controlling part 7. Then, a plasma flame 14 by the sample vapor is formed by microwave energy of the waveguide 13 and a spectroscopic analysis is made. By this constitution, a highly sensitive and accurate spectroscopic analysis by using the plasma flame of the sample vapor converted into high density in the torch 10 is performed.
