(4) Surfactants such as SDS and Brij-35 can also be added to the eluent. However, since surfactants tend to remain on the column, solvent replacement after their use takes a longer lime than replacement from general solvents.
- Page 5 Operation Manual Shodex Asahipak GF-HQ series Version 2106029E (5) Viscosity of high molecular weight compound is largely influenced by its molecular weight and concentration. Samples with high viscosity cause peak broadening and elution delay, and this makes it difficult to obtain their accurate molecular weight distributions. In general, the larger the molecular weight of the compound, the higher its viscosity becomes.

If a GF-7M HQ was used together with columns with different pore sizes, this changes the mixing ratio of the gels and consequently it may deform the linear calibration curve.
