Solid-phase extraction column (silica gel-based polar solid phase FL) 1000mg/6mL 30 pieces FL-1000-6 1 box (30 pieces)

The solid phase is packed with Florisil, a common cleanup agent. It is a selective adsorbent consisting of magnesium-silica gel activated at 675°C. It has high polarity, high activity and excellent porosity, and can retain compounds with low to medium polarity. It can be used with most pesticides including chlorine, nitrogen and phosphorus compounds. Suitable for viscous samples.
