10259 IUPAC Gold Book - stir bar sorptive extraction 10.1351/goldbook.10259 10259 current 1 Extraction of compounds from solution by a sorbent coated magnetic stir bar by rapid stirring (direct immersion) or by exposure to the headspace above a sample (headspace extraction). Related devices for simultaneous stirring and sampling include rotating disc, stir rod, and stir membrane devices. Rapid stirring accelerates mass transfer overcoming some of the limitations of diffusion controlled mass transfer in sessile solutions. headspace https://goldbook.iupac.org//terms/view/10198 headspace extraction https://goldbook.iupac.org//terms/view/10267 sorbent https://goldbook.iupac.org//terms/view/10163 PAC, 2016, 88, 517.
