Description

General description

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

• Tri-layer SPE tube that contains Supelclean ENVI-Carb (upper layer), SAX (middle layer) & PSA (lower layer) SPE sorbents (separated by PE frit)
• Developed to offer superior clean up when conducting multi-residue pesticide analysis from food (e.g. agricultural products, meats, etc.).
• ENVI-carb has a strong affinity towards planar molecules, and can isolate/remove pigments (e.g., chlorophyll and carotinoids) and sterols commonly present in foods and natural products
• Supelclean PSA has a strong affinity and high capacity for fatty acids, organic acids, and some polar pigments and sugars
• Supelclean SAX offers additional ion-exchange exchange capacity for removing matrix components that may induce ion-suppression or enhancement during GC 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...

Solid Phase Extraction: Normal Phase Methodology

In order for polar retention to occur between the sorbent and the sample, the analyte must be introduced to the SPE device in a non-polar sample or mobile phase environment. Therefore, typical sample...

Solid Phase Extraction: Reversed-Phase Methodology

Reversed-phase SPE is considered the least selective retention mechanism when compared to normalphase or ion-exchange SPE. In other words, it may be difficult for a reversed-phase method or bonded ch...
