spray extraction (method)

Explanation:
A new sampling technique is described, where volatile organic compounds are extracted from an aqueous phase into the gas phase using a spray process. The formation of droplets during this spray process enormously increases the total interfacial area between the liquid and the gaseous phase. Using a spray extractor, volatile organic compounds dissolved in water can be sampled to perform. gas chromatographic / mass spectrometric analysis.

Spray-drying, the solvent evaporation method and the aerosol solvent extraction system (ASES) were used to study the influence of the preparation method on residual solvents in microspheres. http://cat.inist.fr/?aModele=afficheN&cpsidt=3077723

The "aerosol solvent extraction system (ASES)" may be a possible answer, because aerosol is a pressurized suspension, which may relate to "spraying" in some sense.

Variations of this process include the aerosol solvent extraction system (ASES), which involves spraying the solution through an atomizing nozzle as fine droplets into supercritical carbon dioxide (Jung and Perrut, 2001). The dissolution of carbon dioxide in
the liquid droplets leads to large volume expansion of the liquid and consequently the reduction of the dissolution power of this liquid and the existence of large supersaturations and thereby the formation of small solute particles. http://72.14.235.104/search?q=cache:iE67_x0dvnsJ:www.uic.edu...

The aerosol solvent extraction system (ASES) is a method based on solvent extraction using supercritical carbon dioxide for the preparation of microspheres.

In other words, the ASES is a variation of the conventional solvent extraction method wherein an aerosol is used instead of a solvent.

Notes to answerer

Asker: Thank you Shirley. I did try with "spray extraction" but couldn't find any information of it being used in microsphere preparation. The description you provided (thank you for having it here, really nice :-) obviously has nothing to do with the method described in my document. Well, I may just use "spray extraction" anyway. If it is not the right one than it is the author's fault not mine, right?

Asker: Hi Shirly, thank you so much. I checked out this one before. However it is based on aerosol, while on the method described in the document it is all in liquid phase. Still doesn't look like it. Looks like I may have to stick with "spray extraction". :-)
