Inorganic adsorption phase

1、Florisil 

Florisil is a highly selective adsorbent that has extensive utility in sample preparation, preparative and analytical chromatography. It was used for AOAC, EPA and other methods designed for pesticide residues, separation, internal secretion and the separation of oil, PCBs, PAHs, and the separation of nitrogen compounds and antibiotic substances in hydrocarbons.

Sorbent Specifications: Particle size: 150-250 μm

2、Alumina

Alumina is an extremely polar sorbent, like silica. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalized silica. The small particle size of the Alumina range ensures high extraction efficiency even when small bed masses are used.
