electrothermal vaporizer

An electrothermal vaporizer (ETV) is a device which is heated, to the temperature required for analyte vaporization, by the passage of electrical current through its body. The ETV is used as a sample introduction device for liquid and solid samples into a spectroscopic excitation or ionization source such as a flame or plasma discharge. The combined technique allows for the independent control of the vaporization parameters and the atomization/ionization parameters. Combined techniques often used are: ETV-ICP-AES, ETV-ICP-MS, ETV-MIP-AES
