The influence of oxygen flooding on the sensitivity of U~+,UO~+and UC)_2~+was checked by using uranium metal and uranium particle(CRM U200)samples.The major and minor isotopic ratios of uranium bearing particles were measured by U~+,UO~+and UO_2~+.The result shows that the use of oxygen flooding technique has no effect on the sensitivity of U~+and the isotopic ratio
The influence of oxygen flooding on the sensitivity of U ~ +, UO ~ + and UC) _2 ~ + was checked by using uranium metal and uranium particle (CRM U200) samples. The major and minor isotopic ratios of uranium bearing particles were measured by U ~ +, UO ~ + and UO_2 ~ + .The result shows that the use of oxygen flooding technique has no effect on the sensitivity of U ~ + and the isotopic ratio
