摘要：
Gelatin films containing water-soluble salts of lithium, rubidium, strontium, or copper were analyzed by secondary ion mass spectrometry. Calcium and vanadium organometallic compounds in an epoxy resin were similarly analyzed. A linear relationship between positive secondary ion intensity and ion concentration was observed over several decades of ion concentration and at absolute concentrations as low as 1 wt ppm. These standards can be used for quantitative analysis of tissue or other biological material in epoxy resins, providing a highly sensitive method for simultaneous quantitation and localization of elements. © 1979.
