What controls iron isotope fractionation in an acid mining pile?Staubwasser M
Fractionation is needed to purify mixtures. While single elements cannot be fractionated, rarely any elements in nature are found isolated without other elements. By fractioning the natural mixture, the scientist is able to purify the more valuable or necessary element from the mixture. For example...
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
What is the isotope notation for lithium? What is a fissile isotope? What is the nuclear symbol for carbon-13? Where is the atomic number located in the isotope symbol? What isotope has 8 protons, 8 neutrons, and 8 electrons? What is isotope fractionation? What are the elements of an is...
Isotope Fractionation: Why Aren't We What We Eat? The isotopic composition of an element records information about its history. Given a fossil, it is possible to analyse the isotopic composition of the ele... DA Schoeller - 《Journal of Archaeological Science》 被引量: 276发表: 1999年 Zoolog...
Isotope ratio mass spectrometry is a specialized method used to obtain information about the biological, chemical, and geographic origins of substances. The isotope ratios of elements such as N, C, oxygen, hydrogen, and sulfur can become locally depleted or enriched due to different thermodynamic an...
Non-thermal mass ablation such as Coulomb explosion and direct chemical bond breaking that represents the true chemistry of the sample and is conducive in reducing the elemental/isotopic fractionation. An ideal size distribution (20 ~ 200 nm) of the ablated particles that are readily transported to...

As in the case of conventional isotope analysis in a monoisotopomer, if the abundance of one of the two PIE isotopes in a diisotopomer is a small quantity, two main species of diisotopomer molecules are used, not taking into account the quantity of molecules with two atoms of a minor ...
