Comparison between the use of direct current glow discharge mass spectrometry and inductively coupled pasma quadrupole mass spectrometry for the analysis of trace elements in nuclear samples

摘要

The quantitative detennination of trace ele- ments in nuclear samples by GDMSand ~CP-MS is pre- sented and compared. Spectral interferences, matrix ef- fects, detection .limits, precision and accuracy are dis- cussed. Results for selected samples demonstrated that both1echniques are complementary. The use of a multi- standard solution provides the most accurate results in ICP-MS, whereas in GDMS this is achieved by relativ~ sensitivity .factors (RSF) matrix matched. Neveft.heless, the use of standard RSF allows a fast screening.
