Enviro-Clean® polymeric extraction sorbents are formulated with an ultra-clean, highly cross-linked styrene and divinylbenzene polymer sorbent. The sorbent can be functionalized with many of the same phases as our silica based sorbents. possibilities include standard ion exchange functionalities. Enviro-Clean® particles have an average particle size of 30 microns with enhanced loading capacity. This higher capacity translates into lower requirements for bed mass. The Enviro-Clean® sorbent also eliminates the need for the initial column conditioning step. All of these attributes ultimately result in improved cost to the end user.
