B&M Florisil ni adsorbent florisil-mgo SiO2 ya silicone ihujwe na magnesium oxyde, igizwe nibice bitatu: dioxyde ya silicon (84%), okiside ya magnesium (15.5%) na sodium sulfate (0.5%). Kimwe na gelika silika, adsorbent niyamamaza rya polarite ikomeye, ibikorwa byinshi hamwe na alkaline nkeya. Ibikoresho bya polar birashobora gukururwa

kuva ibisubizo bidafite inkingi kuri adsorb polarite nkeya hamwe na intera-polarite ivanze bivuye mubisubizo bidafite amazi. Florisil yuzuza granule irashobora gufata ibyitegererezo binini byihuse, mugihe rero icyitegererezo ari cyiza cyane, kirashobora gukoreshwa aho gukoresha inkingi ya silika.

Mubyongeyeho, mugukoresha inkingi ya alumina, niba aside ya lewis ya alumina ibangamiye ibiyikuramo, irashobora gusimbuza ibicuruzwa bya alumina na Florisil.
