摘要:

We developed an interfacial device to couple hydride generation with mass spectrometry. Semimetals in sample solutions were reduced to gaseous hydrides by sodium borohydride and the generated hydrides were condensed in the interface device. The evolved hydrides were introduced into a GC-MS spectrometer. Detection limits for the semimetals were 1 ng for As and Sb, and 5 ng for Ge and Sn on the basis of mass chromatograms of the respective hydrides.
