The IMS 1280 is capable of performing multicollector analyses for all elements heavier than H.

Capabilities for the measurement of isotope ratios using the CAMECA IMS 1280 at The University of Western Australia are outlined below, assuming sample mounts are well-prepared.

(-) Indicates that the method is currently being evaluated.

1 Smaller spot sizes possible at the expense of longer analysis time or lower precision.
2 External precision (1 SD).
3 Analysis time depends on spot size and precision requirements as well as sample mount quality.
4Single crystal precision: precision on multiple grains of magnetite and hematite may suffer for due to crystallographic effects.

FURTHER INFORMATION

The CAMECA IMS 1280 can also perform depth profiles and bulk quantification analyses provided that suitable standards are available.
