Reliable, Productive Ion Microprobe The SHRIMP IIe and SHRIMP V sensitive high resolution ion microprobes.
Developed in collaboration with the Australian National University (ANU), these instruments set the standard for accuracy, reliability, productivity and lowest total cost of ownership in SIMS instruments around the world, particularly for geoscience applications.
The SHRIMP instruments are designed for in-situ measurement of elemental and isotopic compositions of micron-scale areas on the surface of solid samples, based on the principles of secondary ion mass spectrometry (SIMS). The analysis of geological samples is complicated by the presence of complex isobaric interferences that require high mass resolving power to separate the beams of interest. The high mass resolution of SHRIMP instruments is achieved by the use of a large doublefocusing mass spectrometer with energy and mass refocusing.
