X-Ray: Analysis: Seeing Straight Through

Any analytical method that can be carried out without damaging the samples is attractive for pharmaceutical manufacturers. It is not surprising, therefore, that interest is growing in industrial X-ray analysis. This nondestructive analytical technique offers both depth of penetration and reasonably high resolution, making it possible to capture the internal geometric data of a sample along with its density distribution, information that can be useful for process and design verification, product-quality analysis, foreign-material determination (metal, glass, organics), fill-level confirmation, and missing-components detection. In addition, with three-dimensional computed tomography imaging, it is possible to get a true three-dimensional view of the inside of a tablet, capsule, gelcap, or any type of solid or semisolid dosage form. Packaging materials–from medicine bottles to syringes–can also be evaluated.

What is your experience withX-ray analysis of solid or semi-solid dosage forms? Have you found it useful for identifying the source of inconsistencies in the disintegration of fast-dissolve formulations, or perhaps the improper functioning of your syringes or pill container seals? What other applications might there be for X-ray imaging in pharmaceutical manufacturing? What are its limitations? How might it be improved?
