What is PMI?
PMI or Positive Material Identification is to verify that the given material is according to specification. It is however not recommended that PMI be done on an item that has no material certificate. Each machine has its own characteristics.
Method of Inspection | Applications
X-ray Fluorescence (XRF) instruments work by exposing a sample to be measured to a beam of X-rays. The atoms of the sample absorb energy from the X-rays, become temporarily excited and then emit secondary X-rays. Each chemical element emits x-rays at a unique energy.
LIBS laser OES uses high-energy laser pulses to charge the atoms within a sample. The plasma light that is subsequently emitted shows spectral signatures of the present elements. Similarly to spark OES, laser OES provides a computer software system with light intensity data
