摘要：

Relative sensitivity factors (RSF) are studied for impurity elements in metal samples with the use of laser mass spectrometry in the power density range of 1 to 3 multiplied by 10**9 W cm** minus **2 for the focused laser beam. Metallic impurities are found to have RSFs near unity, while nonmetallic impurities are less efficiently ionized relative to iron. The results indicate uniform sensitivities for all the elements may be expected as the power density reaches 5 multiplied by 10**9 W cm** minus **2, in agreement with earlier studies.
