SPE - Insufficient yield?

Insufficient yield?

- Poor compound/stationary phase interaction (ill-suited adsorbent, poor choice of wash or elution solvent).
- Variable analyte elution (incorrect elution solvent, background interactions with substrate, incorrect wash solvent).
- Insufficient sample pre-treatment.
- Loss of analyte (insufficient adsorbent capacity, excessive sample volume).
