We compared micro-PIXE (Particle induced X-ray Emission) and SR-XRF techniques using plant samples with prior micro-PIXE analysis experience, using organic, inorganic, and mixed samples. This comparison evaluated the characteristics of both IBA technology and synchrotron radiation analysis techniques for biological samples, and assessed the feasibility of developing a high-precision analysis protocol for trace elements in biological materials through the complementary use of both methods. We compared the beam probe focusing patterns, analytical sensitivity for each element, and sample damage caused by irradiation. Current results suggest that micro-PIXE analysis may provide more suitable analytical results for life science applications in terms of resolution and sample damage.
