Synthetic dyes are by far the most widely applied colourants in industry. However,
environmental and sustainability considerations have led to an increasing efforts to …

A current economic trend is to highlight natural resources, and many plant species are rich
sources of anthraquinones. The latter are natural compounds that have various biological …

Since the development of the transistor in 1948, analytical research has led to tremendous
advances in instrumental techniques for organic analysis, particularly in the areas of …

Recent advances in analytical chemistry have turned it into a virtually unrecognizable
science compared to a few decades ago, when it lagged behind other sciences and …

We examine the evolution of supercritical fluid extraction (SFE) since 1990 in order to
pinpoint the reasons for its rare implementation by routine analytical laboratories despite its …

The last 20 years have seen an intense interest in the use of supercritical fluids in separation
science. This started with the introduction of commercial instruments first for packed and …

Supercritical fluid extraction (SFE) is a relatively new technique in the field of analytical
chemistry, having evolved in the last decade as an alternative method of preparing samples …

In this paper, the errata for a published paper, titled “Microwave-assisted extraction of
antioxidative anthraquinones from roots of Morinda citrifolia”, authored by Surasak …

La evolución de la Química analítica en las últimas décadas la hace actualmente casi
irreconocible respecto a su situación a mediados de este siglo, época en que su desarrollo …

Supercritical fluid extraction (SFE) collection efficiences of 66 compounds with a wide range
