Shrimp - cool instrument - Aussie invention.
Thesensitive high-resolution ion microprobe(alsosensitive high mass-resolution ion microprobeorSHRIMP) is a large-diameter, double-focusingsecondary ion mass spectrometer(SIMS)sector instrumentthat was produced by Australian Scientific Instruments inCanberra, Australiaand now has been taken over by Chinese company Dunyi Technology Development Co. (DTDC) in Beijing. Similar to the IMS 1270-1280-1300 large-geometry ion microprobes produced byCAMECA, Gennevilliers, France and like other SIMS instruments, the SHRIMPmicroprobebombards a sample under vacuum with a beam of primaryionsthatsputters secondary ionsthat are focused, filtered, and measured according to their energy and mass.
The SHRIMP is primarily used for geological and geochemical applications. It can measure the isotopic and elemental abundances in minerals at a 10 to 30 μm-diameter scale and with a depth resolution of 1–5 μm. Thus, SIMS method is well-suited for the analysis of complex minerals, as often found inmetamorphicterrains, someigneous rocks, and for relatively rapid analysis of statistical valid sets of detrital minerals from sedimentary rocks. The most common application of the instrument is inuranium-thorium-lead geochronology, although the SHRIMP can be used to measure some otherisotoperatio measurements (e.g., δ⁷Li or δ¹¹B^[1]) and trace element abundances.

"now has been taken over by Chinese company Dunyi Technology Development "
somewhat sad that these things are allowed to happen, imo.
