Samples were heated under vacuum at 240 °C for 1 h to drive off water vapor and other atmospheric gases, and then combusted in ultra-high-purity (UHP) O, respectively, to remove sorbed atmospheric C species.
Graphite targets were stored in UHP Ar until measurement by accelerator mass spectrometry (AMS) to avoid potential interaction with atmospheric gases.
Its services are open to all interested users, whether involved in research or administration or from the private sector.
Since its first use in the 1940s radiocarbon dating has been the most accurate method of dating ancient objects and artifacts.
The researchers at the Oeschger Centre use MICADAS among other things to date samples, monitor environmental radioactivity and analyze CO emissions.
While enthusiasts across the world pored over the Voynich manuscript, penned by an unknown author in a language no one understands, a research team at the University of Arizona solved one of its biggest mysteries: When was the book made?
was incorporated as a not-for-profit research organization in 1964.
The Company conducts research in the field of chemistry as it concerns the science and technology of sulfur and its compounds with particular emphasis on the production, processing and utilization of sour natural gas, sour crude oils, oil sands and their related products.
Much of the current focus is on energetically efficient and environmentally sound recovery processes as well as issues around the handling and transportation of elemental sulfur.
ASRL is supported and governed by a broad cross-section of the petroleum-based energy industry and specific sulfur production and supply businesses from Canada, The United States and much of Europe as well as The Middle and Far East.
C laboratories in the world, and the proportional counter that he developed broke new ground: the device was so accurate that for the first time even minute amounts of radioactivity could be measured, making it possible to conduct research into a completely new set of environmental archives.
