Abstract

The idea of pre-filters to quadrupole mass spectrometers was introduced by Brubaker and it has now gone into common use. The contamination of the filter is reduced and the sensitivity is enhanced by this method. The sensitivity of a QMS having 10 cm rods in different combinations with and without pre-and post-filters was measured quantitatively. The advantage of pre-filters is evident.
