The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one,...
Chemical element - Cosmic Abundances, Elements, Periodic Table: The relative numbers of atoms of the various elements are usually described as the abundances of the elements. The chief sources of data from which information is gained about present-day ab
a由表2的发射光谱元素分析测试结果可知,3个润滑油样品中添加剂的含量相差很大。 Emission spectrum ultimate analysis test result may know by Table 2, in 3 lubricating oil samples the chemical additive content difference is very big.[translate]

The elementome—the full spectrum of elemental content—of urinary calculi is emerging as a new concept in stone research. Here, Ramaswamy et al. summarize current knowledge of the elementome of calcium-based urinary calculi and highlight study results o
The Mg content in Mg–N–C is up to 1.32wt% as determined by the inductively coupled plasma atomic emission spectroscopy (ICP-AES) analysis, and no extrinsic Fe, Co, Ni is detected (below 0.01wt%) (Supplementary Table 8). The valence states of elements in Mg–N–C are investigated. ...

They are either being incredibly honest, or they really don't understand what they're saying when they list what amounts to nearly the entire periodic table on the label, as the "trace minerals" they contain. Here is the list in all its glory, typed in by my daughter in exchange for...
low asFX,5th = 3 × 10−15 erg cm−2 s−1. If a uniform-in-the-logarithm prior on the flux were adopted, this would extend to even lower values. Chandra and XRT fluxes are converted to 1 keV flux densities using the best-fit spectrum (Extended Data Table2)...
