Описание: 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 techniques. However, advances in analytical science have been far from universal: while innovations in instrumentation and data acquisition and processing systems have reached unprecedented levels thanks to parallel breakthroughs in computer science and chemo- metrics, progress in preliminary operations has been much slower despite their importance to analytical results. Thus, such clear trends in analytical process development as automation and miniaturization have not reached preliminary operations to the same extent, even though this area is pro- bably in the greatest need. Improvement in preliminary operations is thus an urgent goal of analytical chemistry on the verge of the twenty first century. Increased R&D endeavours and manufacture of commercially available automatic equipment for implementation of the wide variety of operations that separate the uncollected, unmeasured, untreated sample from the signal measuring step are thus crucial on account of the wide variability of such operations, which precludes development of all-purpose equipment, and the complexity of some, particularly relating to solid samples. Supercritical fluid extraction opens up interesting prospects in this context and is no doubt an effective approach to automatioI1 and mini- aturization in the preliminary steps of the analytical process. The dramatic developments achieved in its short life are atypical in many respects.

Описание: Like fractional distillation, chromatography relies on the relative movement of two phases, but in chromatography one is fixed and is known as the stationary phase; Chromatographic methods may be classified first according to the nature of the mobile phase and, second, according to the nature of the stationary phase.

Описание: The use of supercritical fluids in analytical chemistry is still grow- ing. The advantages of supercritical CO , such as having dif- 2 fusivity like a gas and solvating power depending on temperature and pressure, are also valid for other fluids and modified fluids.
