Separation effect of EPRUI GPC Media EPRUI-X3 V.S. International renowned brands S-X3
EPRUI gel permeation chromatography media can be used for different eluent and different linear flow rates. The polystyrene beads with low cross-linking degree (1% and 3%) have stronger swelling ability and exclusion limit. However, the particles are soft and have poor pressure resistance, which is suitable for low linear velocity. While the gel beads with high crosslinking degree (8% and 12%) have higher mechanical strength, weaker swelling ability, lower exclusion limit, which can tolerate large linear velocity. Be sure to swell thoroughly before applying gel chromatography packing, and do not drip during application. Once the gel pack is dried, voids and faults are formed in the column, resulting in reduced separation and resolution.
