摘要：SummaryA laser microdissection system was used for isolating fission track stars to improve the cutting efficiency in the FT-TIMS particle analytical technique. The background interference of track detectors to determine isotopic ratios was studied. Several swipe samples were successfully measured for particle analysis by FT-TIMS. The results show that the laser microdissection system could effectively improve the ability of FT-TIMS particle analytical technique.
