Single Calibration

A new type of calibration standard has been developed for X-ray fluorescence analysis of thin samples. Each standard consists of a polymer film containing a single calibration element. The film is cast from a homogeneous solution containing known amounts of an organometallic compound and a polymer. Polymers of cellulose acetate-propionate and polystyrene are used because of their low moisture affinity. The films have a low (2-4 mg/cm2) mass per unit area for minimal X-ray attenuation. Standards of V, Co, Hi, and Pb have been successfully made. Typical concentrations of 20 μg/cm2 yield excellent spectra with a low background. The method shows promise for making standards of additional elements.
