 note = {We originally developed a preparation method for samples of automobile engine lubricating oil (liquid sample) specifically designed for in-air particle induced X-ray emission (PIXE) analysis with Helium ions. In the developed preparation method, target samples were fixed by making the oil sample sandwiches with 1% collodion solution based ethanol. With this analytical method, elements such as Al, Si, P, S, Cl, Ca and Zn can be detected from the oil samples, while Si, P, S, Ca and Zn were the elemental components of the oil additives},
