Overview Inductively coupled plasma-mass spectrometry (ICP-MS) is one of the most powerful techniques used for elemental analysis in environmental applications. It provides the advantage of low detection limits, easy quantification and high throughput. However, experience and best practices are necessary to achieve optimum results. This manuscript focuses on environmental regulations for trace ...

A series of new norspermidine derivatives, both nonionic and cationic, have been obtained. Structures of the synthesized compounds have been established by FTIR, H NMR, C NMR, 2D NMR, mass spectrometry and elemental analyses. Physicochemical and antimicrobial properties have been discussed.

This paper presents multi-element Stochastic Reduced Basis Methods (ME-SRBMs) for solving linear stochastic partial differential equations. In ME-SRBMs, the domain of definition of the random inputs is decomposed into smaller subdomains or random elements. Stochastic Reduced Basis Methods (SRBMs) are employed in each random element to evaluate the response statistics. These elemental statistics...

The compositions and transfer processes affecting coastal sea sediments from the Seto Inland Sea and the Pacific Ocean are examined through the construction of comprehensive terrestrial and marine geochemical maps for western Japan. Two-way analysis of variance (ANOVA) suggests that the elemental concentrations of marine sediments vary with particle size, and that this has a greater effect than...

Most analytical methods commonly used for organic materials also apply to silicones. Extensive reviews have been published about the different analytical techniques that are applicable for detecting and characterizing silicones [1]. The focus here will be on methods as they relate to typical application problems; some of these are commonly used methods. Others, such as elemental analysis and th...
