摘要
A new boron-silicon gel ion emitter is developed for lead isotope analysis. As a result, a sensitivity of about 10^-7As/μg can be obtained, which permits mass spectrometry to be conducted for lead in the order of 10 nanogram. The mass spectrometry bltnk weight of lead is about 0o2 nanogram. As compared with zirconium-silicon gel the ion beam from lead is more stable.
