Relative sensitivity factors (RSFs) in the analysis of glow discharge mass spectrometry were determined for Fe-based and Ni-based alloys. From 12 Fe-based alloys and 15 Ni-based alloys, pin-shaped and disk-shaped samples were prepared. RSFs of 42 elements in Fe-based alloys and 35 elements in Ni-based alloys were determined using both pin-shaped and disk-shaped samples. The effect of the matrix on RSFs is not recognized. The values of RSFs agree quite well with previous work. However, a systematic deviation of the values of RSFs has been recognized between pin-shaped and disk-shaped samples. This deviation is expressed well by a linear relation. RSFs for disk-shaped samples are obtainable from those for pin-shaped samples using the linear relation and vice versa.
