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).
Notes:
- 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.
