Off-line supercritical fluid extraction for solid matrices,has led to a large number of applications, a diverse range of analytes being reported (.;.;.). Moreover, SFE of environmental matrices constitutes one of the largest groups of applications and has been previously reviewed (.;.;.;.;.). In this chapter the discussion of analytical applications of SFE

In spite of this view, and considering supercritical fluid extraction (SFE) has been available since about 1982, it is interesting to note that the vast majority of reported SFE m

However, there is currently an even greater emphasis on the time an analysis takes, and this has led to the development of automated commercial extraction methods using solvent, microwave-assisted and supercritica

Three major advantages of coupling SFE with chromatography are that:

Economically, SFE equipment is expensive when compared with the traditional approach of Soxhlet extraction. Environmental concern over the use of hazardous and chlorinated solvents, and the cost of solvent disposal, should mean that th

This chapter reviews SFE instrumentation as it applies to the analytical laboratory.
