karakteristisk röntgenstrålning PIXE (Particle Induced X-ray Emission) existerade ännu inte, men Sven Johansson svarade redan på 60-talet för flera stora vetenskapliga insatser. (PIXE = Particle Induced X-ray Emission) metod för grundämnesanalys vid låga koncentrationer. Metoden används bl.a. för analys av borrkärnors Räisänen, J. A. (1986).

Several kinds of excitation beams produce X-rays with energies characteristic of the target elements. Photon excitation (by X-rays) gives rise to X-ray fluorescence spectroscopy.

Unlike EDX, PIXE can also be performed in air. Since its birth, the extensive use of PIXE has been limited by the use of large accelerators. PIXE-metoden är ett snabbt och rutinmässigt sätt att ta reda på vilka grundämnen som finns i ett okänt prov. Speciellt analyserar vi aerosolfilter där luft sugits genom filtret och gett en beläggning på filtret. Detektionsgränserna på filter är ca 0.5 ng/cm 2 i det känsligaste området.
