Determination of ten sulfonamides in honey using tetrahydrofuran Salting Out Liquid Liquid Extraction and monolithic silica column

- The extraction of sulfonamides from honey was performed using tetrahydrofuran.
- The extraction does not require solid phase extraction or solvent evaporation.
- The stability of derivatized samples has been improved.
- Monolithic C18 column was used to separate derivatized sulfonamides.
