What is the functional group on the Supelclean LC-SAX SPE, Product 57017?
The Supelclean LC-SAX SPE functional group is an aliphatic quaternary amine bonded to silica, with a chloride (Cl-) counter-ion; the capacity is approximately 0.2 meq/g (milliequivalents per gram).
How can analytes be eluted from the Supelclean LC-SAX SPE, Product 57017?
The most common elution strategy with the Supelclean LC-SAX SPE is by pH manipulation. Start by using a buffer with the pH adjusted to at least 2 pH units above the molecule’s pKa. Methanol may be added to disrupt secondary interactions. Elute with 100 μL aliquots, at a reduced flow rate of approximately 1-2 drops/second.
