The soils near the abandoned Shimen Realgar Mine are characterized by containing extremely high contents of total and soluble arsenic. To determine the microbial reactions and environmental factors affecting the mobilization and release of arsenic from soils phase into pore
实验方案
Normal-phase SPE separates analytes based on polar interaction with sorbents in diverse sample matrices.
相关内容
SPE retention mechanism in this case is based on the electrostatic attraction of charged functional groups of the analyte(s) to oppositely charged functional groups on the sorbent.

How can analytes be eluted from the Supelclean LC-SAX SPE, Product 57017?
1 answer-
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.
