InertSep Series

InertSep Sorbents List

Polymer-based Sorbent Specifications

To conduct solid phase extraction it is necessary to choose a sorbent best suited for the nature of your target compound and sample matrix. The advantages of polymer-based sorbent are the availability in the wide pH range and the absence of secondary interaction which can occur with silica-based sorbents.

Silica-based Sorbent Specifications

Silica-based SPE sorbent materials are cheaper and have higher physical strength compared with polymer-based sorbent materials. Silica offers a wide variety of separation mechanisms using a combination of primary functional group interaction with secondary interactions due to the nature of silica-base.
