Abstract

The most difficult problem for accelerator mass spectrometry is the rejection of stable atomic isobars. The intensity of isobaric interference is expected to become a problem for ³⁶Cl measurements with the use of new high-intensity ion sources. Although better chemical separation may be possible through improved sample preparation, the device expected to help most with this problem is the gas-filled magnet. We tested a gas-filled Enge split-pole spectrograph combined with a multiplate gas ionization detector for the separation of ³⁶S from ³⁶Cl and obtained an isobar separation of about two orders of magnitude better than that possible with the detector alone.
