DESOLVATION SAMPLE INTRODUCTION DEVICE AND DESOLVATION SAMPLE INTRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a desolvation sample introduction device and desolvation sample introduction method in which, upon the analysis of an atomic spectrum using plasma as an excitation source or ionization source, it is possible to improve the nonuniformity of a dispersion state of an outflow of sample droplets from an external desolvation sample introduction device outside the plasma.;SOLUTION: In order to introduce sample droplets sent from a sample introduction pipe 7 to the inside of a plasma torch part 10 efficiently and stably, a proper amount of additive gas (Ar gas) is introduced from an addition gas introduction pipe 9, so that it is possible to improve the gas flow rate and the dispersion state of sample droplets.;COPYRIGHT: (C)2015,JPO&INPIT
