摘要: 用作同位素丰度的比较测量及数据表达的标准样品,或称参考物质,其中某些如由天然矿石制得者被认为并不均匀,例如硫同位素标准样品NBS-122(美国标准局研制的闪锌矿).近年Swart等分析了六个金刚石晶体,观察到碳同位素丰度在分层中有所变异,得总分馏因数α为1.003.

Abstract: 45 samples were taken from different parts of three large gypsum crystalscollected in China. The mass spectrometric analysis indicated an overall isotopic fractionationfactor for 34S, α= 1.003±0.001.
