TL;DR: In this paper, a modified version of the Adams fusion method was used to deposit IrO 2 on the support surface and a series of electrocatalysts were prepared with a composition of (IrO 2 ) x (TaC) 1− x, where x represents the mass fraction of irO 2 and was equal to 0.1, 0.3, 0., 0.5, 0, 7, 0.9 and 1.5.

TL;DR: By exploiting the principle of pooled calibrations and retainment of all outliers it was possible to obtain full correspondence between calibration uncertainty and repetition uncertainty, which for the first time evidences statistical control in experiments with ion chromatography.

TL;DR: In the authors' opinion, the main task of DAC is to promote analytical chemistry, e.g. by attracting more young people to study this exciting field of chemistry and increasing general awareness of the importance of the subject.
Abstract: Modern analytical methods are indispensable in many disciplines, including medicine, biology and environmental protection, as well as being fundamental to chemistry and chemical technology. Nearly 50 % of EU laws and regulations require strict analytical measurements to monitor compliance. M. Grasserbauer expressed this eloquently at Euroanalysis 13 in 2004 in Salamanca in his statement that “analytical chemistry is indispensable to democratic governance”. This is supported by the number of batch analyses per year done in Europe (about 10) and the astronomical amount of data resulting from continuous analytical monitoring. Nearly 70 % of European chemists consider chemical analysis as either the main or an extremely important part of their job description. In the field of analytical chemistry, more than 100,000 papers are generated in Europe alone every year. Therefore, it is not surprising that analytical science was proclaimed as a breakthrough science by the European Association for Chemical and Molecular Sciences (EuCheMS). It is clearly stated in its documents that the need for analytical measurements arises in all research disciplines, industrial sectors and human activities that entail the need to know not only the identities and amounts of chemical components in a mixture, but also how they are distributed in space and time. Recent developments in this area have underpinned major advances in the biosciences, such as genome mapping and diagnostics. Further developments will improve our capability for real-time and remote analysis, and miniaturisation will enhance our ability to undertake in situ and in vivo analysis. Increasing globalisation of analytical chemistry, together with the increasing range of tasks within its remit, puts an escalating burden on analytical chemists with regard to education, research and development of new analytical methods and approaches, their publication and, above all, their practical application in everyday life. The activities of the Division of Analytical Chemistry (DAC) of EuCheMS [1] are focused in this direction and can provide helpful support in addressing these demanding challenges as demonstrated in the following paragraphs. In our opinion, the main task of DAC is to promote analytical chemistry, e.g. by attracting more young people to study this exciting field of chemistry and increasing general awareness of the importance of the subject.

TL;DR: This paper presents a meta-analyses of the chiral stationary phase of Na6(CO3)(SO4)2, which shows clear patterns in the response of the H2O/O2 mixture to carbon dioxide levels in the presence of carbon dioxide.

TL;DR: Students of chemistry aiming at competence in analytical chemistry are faced with numerous subjects such as physics, computing, interfacing, and electronics at a relatively high level in order to devise new methods of analysis using advanced apparatus.
Abstract: Many topics in mathematics and physics are relevant to teaching analytical chemistry, but a few key topics are essential to prepare students for the master level [1–4]. Knowledge of mathematics and physics is important to understand the operation of advanced apparatus and for the interpretation of data. The overall aim of introducing ten European Credit Transfer and Accumulation System (ECTS) credit points for mathematics and ten ECTS credit points for physics in addition to 15 ECTS credit points for analytical chemistry is to maintain education in analytical chemistry at a high level to benefit science and the progress of analytical chemistry. The European Association for Chemical and Molecular Science Division of Analytical Chemistry (EuCheMS-DAC) has suggested a curriculum for the bachelor degree [4]. As the language of science is mathematics, similarly physics promotes the understanding of basic mechanisms and chemical interactions. Analytical chemistry requires a multidisciplinary approach to understanding the art of quantifying chemical species in various mixtures and matrices [2]. Thus, students of chemistry aiming at competence in analytical chemistry are faced with numerous subjects such as physics, computing, interfacing, and electronics at a relatively high level in order to devise new methods of analysis using advanced apparatus.
