Indicate whether each is a characteristic of solid phase extraction (SPE) or solid phase microextraction (SPME). 1. Can be only used for liquid-phase samples 2. Uses a relatively smaller sample volume, (ex. 4 mL) 3. Requires a liquid-phase extraction step after desorption. 4. Uses a relatively large sample volume, (ex. 500 mL) 5. Uses a small fiber or tube coated with a sorbent material. 6. Can be used for both liquid-phase and gas-phase samples 7. Uses a solid adsorbent, such as silica or polymer beads, packed into a column. 8. Solvent-free extraction
