摘要：

Plasma modification studies are carried out using getter reagents as sample matrices in analyzing lanthanum oxide with glow discharge mass spectrometry. Five metals with varying gettering abilities, Ti, Ta, W, C and Ag, are evaluated with respect to removing gaseous interferences from the discharge and enhancing the atomic population of the analyte. Getting action is considered proportional to the metal's sputter yield and its affinity toward oxygen.
