Direct filter vaporization with induction heating-electrothermal vaporization (IH-ETV) and a foam carbon surface
Abstract
An inductively heated electrothermal vaporizer (IH-ETV) sample introduction system was tested using a foam carbon surface with and without a standard air sampling filter employing ICP-AES excitation with a semiconductor based commercial detection system. Liquid detection limits using 10 µl injections were roughly comparable to those obtained using conventional nebulization on the same instrument.
