They were then able to detect amounts of isotope iron-60 after using an accelerator mass spectrometer
The scientists used an accelerator mass spectrometer
to determine the C-14 levels in the alcohol components of 20 Australian red wines with vintages from 1958 to 1997.
Ann McNichol, a WHOI senior researcher, analyzed the samples at the National Ocean Sciences Accelerator Mass Spectrometer
Facility at WHOI.
The researchers used a accelerator mass spectrometer
, which narrowed the age of the book down to 1404 to 1438, in the early Renaissance.
The amount of 14C-labeled vitamin B-12 in the sample is measured with an accelerator mass spectrometer
, which can count single atoms of 14C.
Kenneth Turtletaub, a scientist at Lawrence Livermore National Laboratory, uses an accelerator mass spectrometer
to look at nanostructures for biomarkers of exposure to carcinogenic chemicals, characterizing perturbations at the atomic level.
Each Plantago and Pectocarya sample was pretreated, combusted, and run through the tandem accelerator at the Accelerator Mass Spectrometer
Laboratory (AMS) at the University of Arizona.
The scientists used a highly-sensitive analytical device called an accelerator mass spectrometer
to determine the C-14 levels in the alcohol components of 20 Australian red wines with vintages from 1958 to 1997 and then compared these measurements to the radioactivity levels of known atmospheric samples.
Reddy and colleagues worked with WHOI chemist Bill Jenkins and colleagues at the National Ocean Sciences Accelerator Mass Spectrometer
facility at WHOI to develop an extremely precise radiocarbon-based calibration method for determining if the balance of biofuels and petroleum is correct.
O'Brien's group applied accelerator mass spectrometer
(AMS) dating to 7 of 18 footwear specimens discovered more than 40 years ago in central Missouri's Arnold Research Cave.
