AMS is a technique to count particle that is provided energy at least detectable by accelerating, and this technique is popular in radioisotope analysis. One of the most popular AMS, which contains a tandem accelerator accelerate all particles with same energy, so particle identifications undergo by magnetic field before being detected by faraday cups and particle detectors. Although tandem type AMS is popular, Linear Accelerator (LINAC) type is also AMS. On that AMS, element has different energy with each mass, because LINAC accelerate each nuclear particles, which are selected charge to mass ratio (q/A), with constant speed, and particles are identified and counted by SSD. However applications of these techniques to trace element analysis are several and quantitative analysis is not studied, because ionization efficiency is problem for unknown sample. To solve this problem we considered applying Particle Induced X-ray Emission (PIXE) analysis. Before being AMS unknown sample is analyzed by PIXE, allow using that data as a standard of calibrations in ppm-ppb range. Experimental AMS consist of RFQ (q/A=1/16, input energy is 5 kV/amu, output energy is 214 keV/amu), analyzer magnets, electrostatic lenses, and ECR ion source that generate magnetic field by permanent magnets. We attempt quantitative analysis by calibrated valence and particle distribution charts at ppq.
