IMPROVED METHOD FOR RAPID ANALYSIS OF GOLD |
摘要 |
A method to determine a concentration of a target element in a sample is provide. The method comprises (i) positioning a sample containing a target element with respect to a reference material containing a reference element, (ii) simultaneously irradiating the sample and the reference material with Bremsstrahlung X-rays to thereby produce activated nuclei in the target element and to produce activated nuclei in the reference element, (iii) detecting deactivation gamma-rays' from the irradiated sample and deactivation gamma-rays from the irradiated reference material, (iv) determining a first number of detected deactivation gamma-rays from the irradiated sample and a second number of detected deactivation gamma-rays from the reference material, and (v) determining the concentration of the target element in the sample by first normalising the first number of detected deactivation gamma-rays from the irradiated sample by the second number of detected deactivation gamma-rays from the reference material. The variation of the reference element to target element cross section ratio over a range of electron beam energies is less than a predetermined measurement accuracy. |
