Qualitative x-ray microanalytical studies used to demonstrate calcium in bioprosthetic aortic valves have shown that it occurs in a range of morphological forms. A consistent and reproducible standard for measuring calcium was necessary to investigate whether these forms represented varying concentrations of calcium. To provide such a standard, we tested a series of calcium naphthenate-epon mixtures.
