AbstractAbstract
[en] In recent years, knowledge of the different chemical forms of the elements has gained increasing importance. There has been significant progress in methods that hyphenate chromatographic separations with atomic spectrometry. These hyphenated methods can provide the most complete information on the species distribution and even structure. However, they can be lengthy, relatively costly and difficult to bring to the routine. On the other hand, it is important to remember that chromatographic techniques represent only a minor part of the separation procedures available and, in certain cases, the application of basic chemistry to sample treatments can give quantitative information about specific chemical forms. In this sense, non-chromatographic procedures can provide methods that offer sufficient information on the elemental speciation for a series of situations. Moreover, these non-chromatographic strategies can be less time consuming, more cost effective and available, and present competitive limits of detection. Thus, non-chromatographic speciation analysis continues to be a promising research area and has been applied to the development of several methodologies that facilitate this type of analytical approach. In view of their importance, the present work overviews and discusses different non-chromatographic methods as alternatives for the speciation analysis of clinical, environmental and food samples using atomic spectrometry for detection.

AbstractAbstract
[en] This paper discusses some aspects of the deconvolution and regularization procedures within the least squares method (LSM), taking into account, in every step, the covariance matrices. If the covariance matrices are taken into account, the obtained results are unbiased, the artifacts can be understood, and the goodness-of-fit can be test by the usual chi-square test. (author)

AbstractAbstract
[en] High sensitivity analytical techniques, such as ICP-MS, MIP-AES, XRF etc., in rare earth hydrometallurgy, have drastically developed products quality. However, these offline analysis methods may struggle to achieve real-time feedback. A potential alternative method was investigated to be a new usage of lanthanum analysis through detecting the 1435.8 keV gamma ray in situ, emitted by 138La. A high purity germanium gamma spectrometry was utilized to obtain the experimental minimum detectable concentration (MDC) and the sensitivity (S), which ranges from 4.66 to 4.99 g L-1 and (1.85 to 1.90) × 10-3 cps (g/L)-1, respectively.
