Role of Chemical and Analytical Reagents in Colorimetric Estimation of Pharmaceuticals-A Review

Analytical Methods

Despite the large relative mass difference between different Ca isotopes, the isotopic variability of Ca in natural materials is relatively small. Consequently, high-precision Ca isotope analyses are required to accurately resolve Ca isotope fractionation prior to data interpretation. This chapter summarises techniques which are successfully used to digest samples and to purify different types ...

Analytical methods for nanomaterial characterization

In recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. The properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. Rout...

Analytical Comparison of Methods for Calculating the Completeness of VGI

Spatial data, which is one of the main needs of human societies from business organizations to the general users today, cannot meet the needs of a wide range of users without changing the structure of conventional methods of data registration and updating on a metropolitan scale. Open Street Map, as one of the most successful implementations of the crowdsourcing approach to spatial data with th...
