Abstract

Direct current glow discharge mass spectrometry (dc-GDMS) has been applied for the direct analysis of {237}Np in marine sediment samples from the Irish Sea. The secondary cathode technique was exploited to promote the sputtering of the sediment samples once compacted into a pellet. A certified marine sediment doped with a certified {237}Np solution was used for obtaining matrix-matching samples for calibration purposes. Acquiring 100 points over an integration time of 300 ms a detection limit down to 80 pg g{�1} was obtained. Results on {237}Np were in agreement with those obtained by the determination of {233}Pa by gamma-spectrometry.
