The advantages comparing to other techniques are based on the fast diffusivity of the compounds in the fluid and the supercritical fluid solvating power. These technologies are a good alternative to extraction with liquid solvents such as Soxhlet extraction and ultrasonic extraction and also to gas or liquid Chromatography separation.

Additional Advantages that are consequence of supercritical fluids properties:

• Possibility to work at low temperatures.
• Protection against oxygen and minimisation of oxidation risk in the sample.
• Prevention of artefacts formation produced by chemical reaction.
• Easy control of extraction conditions by changing the pressure and/or temperature: easy adjustable selectivity.
• Fast extraction.
• Reduction or complete suppression of the extract stages of concentration.
