Description of PR Grade Florisil SPE Cartridge

Florisil (Flori silica) SPE cartridge is an adsorbent of silica gel bonded to magnesium oxide. Similar to silica gel, it is a highly polar adsorbent and can extract polar compounds from non-polar solutions. When the sample viscosity is large, it can replace the silica gel SPE cartridge.

The pesticide residue (PR) grade Florisil 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.
