UCT
Solid phase extraction sorbents, specialty chemicals, and chromatographic media
The Selectra line of HPLC columns is created using an ultra-high purity, Type B, spherical silica. This support material minimizes surface activity and allows for high density functional group bonding.

moderately polar analytes that are difficult to resolve on standard C18
phases
- Selectra EtG: designed for maximum retention for polar EtG/EtS
alcohol metabolites
