Chemical stability of a product can change over time. This can be seen in e.g., milk products that do not have the right texture or taste or in metals that break from within. The exact mechanism behind a stability issue may be difficult to pinpoint. If so, one way forward lies in 3D techniques using X-rays as they can reveal changes to products, machine parts or materials at a microscopic or even molecular level. They offer a “toolbox” to help guide efforts towards e.g. durability improvement, product development, or better assessment of warranties.
