Direct analysis of solid samples by electrothermal vaporization inductively coupled plasma mass spectrometry
1994
Abstract The direct analysis of solid samples by electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS) has been demonstrated. This method provides a rapid alternative to traditional means of solid sample analysis, as the sample pre-treatment procedures are eliminated or minimized. Three instrument calibration methods for the solid sample determinations such as liquid standard, standard addition and differing weights of a standard reference material have been investigated. Utilization of standard reference materials for standardization, when available, provided for the best performance for the ETV-ICP-MS system. A simple and easy to use method of introducing the solid sample, with a well-defined mass, into the graphite furnace has been developed.
