Florisil SPE Cartridge
Description
Hawach PR Grade Florisil SPE cartridges are designed for reliable normal-phase cleanup of complex organic extracts prior to GC and GC-MS analysis. Manufactured using tightly controlled 675 °C activation conditions, these cartridges provide stable adsorption performance for EPA 608, AOAC, and routine pesticide residue workflows.
Florisil SPE cartridges are widely used for cleanup of organochlorine pesticides, PCB compounds, amines, ketones, and organic acids in food, agricultural, and environmental laboratories.
Why Florisil SPE is Used in EPA 608 Cleanup
Florisil SPE cartridges provide selective retention of polar matrix interferences while allowing efficient elution of organochlorine pesticides and PCB compounds. Compared with conventional silica sorbents, Florisil offers improved cleanup efficiency for fatty and complex environmental extracts, making it one of the most widely adopted sorbents in EPA 608 and AOAC residue analysis workflows.
The highly polar magnesium silicate surface helps reduce background interference prior to GC-ECD and GC-MS analysis, improving chromatographic cleanliness and analytical reproducibility.
Sorbent Composition & Activation
- PR Grade activated magnesium silicate
- Activation temperature: 675 °C
- Composition: MgO (15.5%), SiO₂ (84%), Na₂SO₄ (0.5%)
- Highly porous polar surface with abundant hydroxyl groups
- Strong retention of polar matrix interferences
- Effective fractionation of halogenated and non-polar analytes
Designed for Consistent SPE Recoveries
Manufactured under controlled activation and packing conditions to minimize lot-to-lot adsorption variability. Optimized particle distribution helps maintain stable SPE flow performance and reproducible analytical recoveries across routine testing batches.

Frequently Asked Questions
What are Florisil SPE cartridges used for?
Florisil SPE cartridges are primarily used for cleanup of organochlorine pesticides, PCB residues, amines, ketones, and organic acids prior to GC-ECD or GC-MS analysis.
Which analytical methods are compatible with Florisil SPE cartridges?
These cartridges are commonly used in EPA 608, AOAC residue analysis methods, and other normal-phase cleanup workflows.
Why is Florisil preferred for pesticide cleanup?
Florisil provides strong retention of polar matrix interferences while allowing efficient recovery of many halogenated pesticide compounds, improving chromatographic cleanliness.
Can Florisil SPE cartridges process aqueous samples directly?
No. Water samples are typically extracted into an organic solvent before Florisil cleanup.
Do you provide OEM and bulk supply support?
Yes. OEM packaging, custom labeling, and bulk sorbent supply are available for distributors, contract laboratories, and analytical kit manufacturers.
