Positive material identification (PMI) is a critical aspect in the quality control process for many organizations and throughout many industries. Defined as the analysis of a metallic alloy to establish composition by reading the quantities of its constituent elements by percentage, the common methods of PMI include x-ray fluorescence (XRF) and optical emission spectrometry (OES).
Required in settings such as petrochemical, power generation, steel/iron foundries, fabricators, and PMI inspection companies, choosing the right approach depends on a few aspects of an organizations metal identification needs.
