摘要:Abstract(#br)Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the determination of minor and major elements present in Cornelian cherry ( Cornus mas L.), as this fruit and its preservatives may be considered as important nutritional supplements. P...

摘要:Abstract(#br)We have developed a new method for the quantification of 11 major and minor elements (Na, Mg, Al, P, S, K, Ca, Cr, Mn, Fe, and Ni) in chondritic meteorites by ICPMS using external calibration with a matrix-matched standard prepared from the Allende Standard Reference...

摘要:Abstract(#br)Two hundred and thirty-three samples from the Hoheneggelsen KB 40 drill core, located 30 km SE of Hannover, Germany, were analysed for 12 major elements, 14 minor elements, degree of pyritization, and S-isotopic composition. This early Aptian sequence consists of th...

摘要:Abstract(#br)Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the determination of minor and major elements present in apple juices. Prior to ICP-AES measurement, samples were diluted with nitric acid or digested in a microwave assisted digestion ...

摘要:... Suitable selection of the analyte isotopes and the use of appropriate instrument settings and of internal standardization makes it possible to determine the major and minor elements in the same test sample dilution. Use of the omnirange device and low-abundance isotopes for t...

摘要:... This initially generates single convection cells, which cause progressive homogenization of some major components. This is the case after 1, 4 and 9 h. After 16 h the 87 Sr/ 86 Sr-isotopic system is homogenized and the starting compositions are fully mixed. Then separate ...

摘要:... The concentrations of Na, K, Ca, Mg and P (major elements) as well as Fe, Mn, Sn, Cu, Ni, Zn, Pb and Cd (minor elements) were determined in 35 commercial vinegar samples using inductively coupled plasma optical-emission spectrometry (ICP-OES). The elements with the highest co...

摘要:Abstract(#br)This study uses 1356 spectra from 452 geologically-diverse samples, the largest suite of LIBS rock spectra ever assembled, to compare the accuracy of elemental predictions in models that use only spectral regions thought to contain peaks arising from the element of i...
