HEMA/HEMA-Bio
Hydrophilic and Polar SEC-Columns
MZ-SEC-columns for aqueous or polar eluents are packed with HEMA- or HEMA-Bio-Gel. They are best suited for the characterization and preparative separation of synthetic polymers, oligomers or additives in aqueous or polar solvents.
Typical applications for HEMA-Gel are:
- polyethylenoxides or -glycols
- polystyrenesulfonates
- polyacrylic acids
- polyacrylamides
- polysaccharides
HEMA-Gel is a hydroxylmethacrylate copolymer which is highly cross linked with ethylenglycoldimethylacrylate. It is fully compatible both with aqueous and polar eluents.
This enables an easy change of eluents as for example:
water -> methanol -> acetone -> THF -> water
