Abstract
Faraday cup efficiencies (FCE's) in the multicollector mass spectrometer were examined with a static multicollection technique. The relative Faraday cup efficiency (RFCE) was estimated by measurement of Nd-isotope ratios with five different cup configurations. The application of RFCE correction to the static multicollection technique will increase the reliability of analytical results by eliminating the errors caused by differences in FCE's, and will also enable us to distinguish which Faraday cups are damaged and should be renewed.
