Positive Material Identification (PMI)

Positive Material Identification (PMI) is the identification and chemical analysis of various metal alloys through nondestructive methods. PMI can be conducted on-site or in the laboratory. Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES).
