Abstract

In the present work, a simple thermospray sample introduction applied in the recently developed μFAES system (where a microburner and flame were created on a microchip (flame-on-a-chip)) was extended with a process based on combined effects of thermospray and evaporation of the formed solid salts. In the used microfluidic system, the mechanisms of the thermospray and evaporation exhibit interesting and new features, which can be utilized in atomic spectroscopy. The effects of several parameters (like flow rates, sample volume and inner diameter of the thermospray capillary) of the sample introduction were investigated.
