Normal Phase PR Grade Florisil SPE Cartridges

Function Group: silicon Hydroxyl
Material character: 60~100 mesh(150-200μm)
Retention Mechanism: normal phase, allowing for the
retention of polar and halogenated compounds


Description of Normal Phase PR Grade Florisil SPE Cartridges

The pesticide residue (PR) grade Florisil solid phase extraction (SPE) cartridge is activated at 675 °C and is a highly polar, highly active porous adsorbent that adsorbs low polarity and medium polarity target compounds. Such as organic pesticides containing chlorine, nitrogen, and phosphorus.
In the pesticide residue detection, the Florisil cartridge has a good effect and low cost and is adopted by the US EPA 608 method and the Chinese Ministry of Agriculture NY/T 761 method.
