Trace Element Analysis by ICP-MS and Chemometric Approach in Some Euphorbia Specie: Potencial to become a Biomonitor
In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...

متن کاملLinear and Nonlinear Multivariate Classification of Iranian Bottled Mineral Waters According to Their Elemental Content Determined by ICP-OES
The combinations of inductively coupled plasma-optical emission spectrometry (ICP-OES) and three classification algorithms, i.e., partial least squares discriminant analysis (PLS-DA), least squares support vector machine (LS-SVM) and soft independent modeling of class analogies (SIMCA), for discriminating different brands of Iranian bottled mineral waters, were explored. ICP-OES was used for th...
متن کاملMulti-Element Analysis of Petroleum Crude Oils using an Agilent 7900 ICP-MS Authors
In the petrochemical industry, certain elements are known to impact the performance and value of the final product, while others have detrimental effects on petroleum refining processes, as in the case of elements which can deactivate or poison catalysts. Consequently, there are several ASTM methods on the elemental analysis of oils, lubricants and fuels. Multi-Element Analysis of Petroleum Cru...
متن کاملMajor element analysis of natural silicates by laser ablation ICP-MS†‡
The complete chemical analysis of natural silicates has previously been accomplished only by combining laser ablation ICP-MS with electron microprobe (EMP) analysis to provide complementary information on major element constituents. Here, we present a method for laser ablation ICP-MS analysis of major elements in silicate glasses and minerals that, when applied using a 193 nm laser system coupl...
