General description

Retention Mechanism: Normal-phase and anion-exchange
Sample Matrix Compatibility: Organic or aqueous solutions

• Dual layer SPE tube that contains both Supelclean SAX (upper layer) and PSA (lower layer) SPE sorbents (separated by PE frit)
• Supelclean SAX is a quarternary amine, Cl- counter-ion.
• Supelclean PSA an ethylenediamine-N-propyl phas that contains both primary and secondary amines.
• Ideal for removing matrix components (fatty acids, organic acids, polar pigments, and some sugars) when conducting multi-residue pesticide analysis in foods
• In compliance with the Luke II method which uses SPE to remove matrix interference and enhancement of pesticides from food for GC-ITMS analysis

Solid Phase Extraction: Ion Exchange Methodology

In order for electrostatic retention to occur, both analyte and sorbent functional groups must be in their ionized form. This is done through strict pH control of the sample matrix. For basic analyte...
