Age determinations using the 235U and 238U radioactive decay series to the daughter isotopes 207Pb and 206Pb, respectively, using the mineral zircon (ZrSiO4), are widely used to decipher geological ...

Abstract: Mass spectrometry plays a crucial role in biomedicine by detecting isotopes, contributing significantly to research, diagnostics, and therapy development. This study introduces IsoFusion, a ...

Shang Xianhe, general manager of Qinshan Nuclear Power, told reporters: "This is the first time China has achieved mass production of carbon-14 isotopes in a commercial nuclear power reactor. From now ...

AFTER repeated failures I have now succeeded in observing the mass rays of zirconium. Their detection is only possible under very favourable conditions with the most sensitive schumannised plates ...

Now, an interdisciplinary team of researchers has demonstrated a way to overcome the challenge: use a new technique—dubbed fragment correlation mass spectrometry—on a mix of parent peptides ...

Based on studying the prompt fission neutron spectrum of the induced fission of plutonium-240, researchers at LANSCE have found discrepancies with nuclear data libraries, especially on the energy ...

China has started mass production of a radioactive isotope widely used in science and medicine, putting the country on the path to ending its near-total reliance on imports. State-run China ...

What are the common types of ion detector for mass spectrometry? A key element to all mass spectrometry (MS) systems is the type of detector 1 used to convert a current of mass separated ions into ...

MS is a form of chemical analysis used to measure the mass-to-charge ratio (m/z) of atoms and/or molecules in a sample. It is also capable of distinguishing between different isotopes of the same ...
