Positive material identification

Source: Wikipedia, the free encyclopedia.

Positive material identification (PMI) is the analysis of a material, this can be any material but is generally used for the analysis of metallic

optical emission spectrometry (OES).[1]

PMI is a portable method of analysis and can be used in the field on components. [2]

X-ray fluorescence (XRF) PMI can not detect small elements such as carbon. This means that when undertaking analysis of stainless steels such as grades 304 and 316 the low carbon 'L' variant can not be determined. This however can be analysed with optical emission spectrometry (OES) [3]
