RELATIVE SENSITIVITY FACTORS FOR CU, AL, AND TI-BASED METALS IN GLOW-DISCHARGE MASS-SPECTROMETRY

Relative sensitivity factors (RSFs) in the analysis of glow discharge mass spectrometry were determined for Cu, Ai and Ti-based metals. Pin- shaped and disk-shaped samples for the respective matrices were prepar ed from the same blocks. A systematic deviation has been recognised be tween the values of RSFs for pin-shaped samples and disk-shaped sample s in all the matrices. The manner of the deviation is quite similar to that in Fe and Ni-based metals as has already been reported and the d eviation in each matrix is expressed by a linear relation. RSFs for di sk-shaped samples are obtainable from those for pin-shaped samples by the linear relation and vice versa.
