Abstract

A thermospray was used as a metal preconcentration device for flame AAS. With 1.0 mL of sample loading, the AA signal was increased about 15 times and with 2.0 mL of sample loading the signal was increased about 30 times compared to a thermospray flame system and more than two order of magnitude compared to a normal flame system.
