Furthermore, we aim to develop the protocols for N isotope analysis by ion microprobe
and by static mass spectrometry in multi-collection mode; these methods will allow us to target micron-sized samples (such as melt inclusions) for N analyses and to improve the analytical precision for coupled N-noble gas studies, respectively.
Sarafian learned that WHOI geologist Nobu Shimizu had developed a technique to measure water trapped in glass pockets in basaltic seafloor rocks, using the Northeast National Ion Microprobe
Facility at WHOI.
The researchers analyzed five different samples at the Northeast National Ion Microprobe
Facility -- a state-of-the-art national facility housed at WHOI that utilizes secondary ion mass spectrometers.
2002, Records of the evolution of the Himalayan orogen from in situ Th- Pb ion microprobe
dating of monazite: Eastern Nepal and western Garhwal, J.
We are also grateful to the Laboratory of Isotope Geology at The University of Georgia and the Sensitive High Mass-Resolution Ion Microprobe
(SHRIMP-RG) team at Stanford University, California (USA).
Louis have used a new ion microprobe
to map oxygen-isotope ratios at very tiny scales within individual dust particles.
This paper describes the initial results of research into the use of uranium-lead (U-Pb) dating by sensitive high mass resolution ion microprobe
(SHRIMP) to `fingerprint' dust using fine-grained windblown zircons separated from soil profiles in the south-eastern highlands of Australia.
The test uses an instrument called an ion microprobe
, which blasts a few atoms from the gem's surface.
USING AN ADVANCED ion microprobe
, scientists at Hughes Research Laboratories, Malibu Beach, CA, have built circuit features as small as 12 nm on resist-coated gallium arsenide wafers.
Uncover the mysteries of the Sensitive High-Resolution Ion Microprobe
Shimizu is a senior scientist in the WHOI Department of Geology and Geophysics, as well as founder and director of the Northeast National Ion Microprobe
Valley of the University of Wisconsin-Madison and his colleagues used an ion microprobe
to measure the ratio of two isotopes, oxygen-18 and oxygen-16, in a sample of the meteorite no bigger than a grain of rice.
