At PMI Analytical Testing Services, we are committed to helping you obtain the pore structure information you need. Because there are multiple techniques and instruments, it is critical at the onset to identify the appropriate method of measurement — we begin by discussing your application with you to determine the method that provides the most comprehensive results. While PMI provides you with a detailed report, our application engineers are always available to discuss and help interpret your results. PMI's Analytical Testing Services Division can accommodate a wide variety of samples, materials, and shapes.
