Application
Amberlite® XAD®-2 may be used as a stationary phase material for the solid phase extraction (SPE) of phenolic acids and flavonols from honey samples prior to their identification by high performance liquid chromatography-diode array detection (HPLC-DAD),[1] phthalate esters (PAEs) from hydroalcoholic food beverages prior to their determination by gas chromatography (GC) equipped with flame ionization detector (FID) as well as ion-trap mass spectrometry detector (IT/MS),[2] benzoic and sorbic acids in quince jam prior to their analysis by isocratic HPLC combined with photodiode array (PDA) detector [3] and organophosphorus pesticides in natural and drinking waters prior to their determination by GC-FID or GC coupled to nitrogen-phosphorus detector (NPD).[4]
用于分子量高达 20,000 的疏水性化合物的多环芳烃吸附剂树脂,具体用途包括酚类和有机物的去除,表面活性剂、芳香化合物和抗生素的回收。可用作催化或金属去除的助剂。经整理的美国环保局版本请参见 Supelpak-2 和 Supelpak-2B。
