Discovery(R) DSC-SAX SPE Tube

Descrição detalhada : Retention Mechanism: Anion-exchangeSample Matrix Compatibility: Organic or aqueous solutions. A polymerically bonded quarternary amine that remains positively charged at all pH levels. Counter ion is Cl-. Ion exchange capacity is >= 0.14 meq/g. Commonly used when extracting weaker anions (e.g., carboxylic acids) that may not bind strongly enough to weaker anion-exchangers. Selectivity can be modified by changing the counter ion with the appropriate buffer during conditioning
