Some Trends in Modern Analytical Chemistry

Trends in Analytical Chemistry, doi:10.1016/j

We report on a Communication of the European Commission to the Council and the European Parliament in 2002, entitled ‘‘Towards a Thematic Strategy for Soil Protection’’, an operational framework for its implementation and an indicator approach, as a basis for the elaboration of priority research areas for soil protection and the management of Europe’s natural resources. From this, we draw the c...

Some new trends in the chemistry of polysaccharides.

The data on the fine structure of polysaccharides should form the basis for understanding on a molecular level the biological role played by carbohydrate systems, but the methods of structural chemistry are not always sufficient. The most general approach for determination of the primary structure of polysaccharides might be the development of standard methods, which involve specific cleavage t...

Standardization of Some Plant-Based Formulations By Modern Analytical Techniques

The chemistry of chromium and some resulting analytical problems.

Chromium, named for its many-colored compounds, exists in the oxidation states of -2 to +6 inclusively. The compounds exhibit a wide range of geometries including square planar, tetrahedral, octahedral, and various distorted geometries. Chromium is found in nature principally as the chromite ore FeCr2O4 in which chromium is in the +3 state. The existence of a particular oxidation state is depen...

Miniaturization in Analytical Chemistry

Miniaturization is rapidly growing, with novel ideas emerging in recent years. Like other fields, analytical systems have been affected by this new technology. Concretely, the capacity to carry out laboratory operations on a small scale using miniaturized devices is very appealing. Micro total analysis systems (mTAS), also called lab-on-a-chip, have renewed interest in scaling laws in the last ...
