Determination of Phenols in Water According to DIN 38407-27
using Bar Sorptive Extraction (SBSE)
DIN 38407-27 is a German standard method for the examination of water, wastewater and sludge for the determination of selected phenols in groundwater and leachate, aqueous eluates and percolates.
After derivatization of the analytes with acetic anhydride to their corresponding acetates and subsequent liquid-liquid extraction, the determination is carried out using gas chromatography/mass spectrometry (GC-MS).
For this application liquid-liquid extraction has been replaced with stir bar sorptive extraction (SBSE) using the GERSTEL Twister.
