摘要：
A second low-energy injection line containing the Isobar Separator for Anions (ISA), a radiofrequency quadrupole reaction cell system, was installed on the 3 MV tandem accelerator system at the A. E. Lalonde (AEL) accelerator mass spectrometry (AMS) Laboratory. The suppression of 36S via anion-gas reaction with NO2 was evaluated for measurements of 36Cl reference materials and a dilution series, using a 3 MV AMS system. The dilution series, with 36Cl/Cl ratios ranging from 10-11 to 10-15, were measured in comparison with external measurement. 36Cl/Cl blank levels of (7 +/- 4) x10-15 were reached. While ISA-AMS is not currently able to achieve sufficient separation for most 36Cl applications, these measurements show progress towards routine measurement of 36Cl and demonstrate the steps required to validate such measurements on lower energy AMS systems.
