Abstract

A method for allowing reproducible, precise, and substantially temperature independent quantitative measurements of one or more high vapor pressure elements in a liquid metal or alloy sample using Laser Induced Breakdown Spectroscopy (LIBS). The method introduces one or more selectively reactive species and a substantially inert carrier gas to modify the local environment at and around the LIBS sampling point of the liquid metal or alloy. This results in a significant and immediate reduction of the vapor effects on LIBS signals of high vapor pressure species in metal or alloy melts, partially eliminating the temperature-dependence of the high vapor pressure elements and their dependence on spurious environmental factors, reducing the associated uncertainty in the LIBS measurements.
