Polymer-based Aqueous SEC
Polymer-based Aqueous SEC Columns from Shodex
- Polymer-based packed columns for aqueous SEC analysis
- Network or pores on the surface of the packing material works as molecular sieve to separate molecules based on their sizes
- To separate molecules solely based on their sizes, it requires an analytical condition without any analyte and packing gel interaction
- The bigger the molecule size, the faster the elution sequence
- Used for molecular weight or molecular distribution determination of macromolecules and qualification of oligomers

SB-800 HQ - Polymer-based packed columns for aqueous SEC (GFC) analysis
- Supports a wide range of molecular weight sample analysis
- The eluent can be replaced with DMF (except SB-802 HQ and SB-807 HQ), enabling the analysis of polar polymers
- Method using SB-804 HQ or SB-805 HQ for gelatin's mean molecular weight determination is comparable with PAGI method (Ver. 10 Japan)
- Fulfills USP L38 and L39 requirements
- SB-802 and 802.5 HQ fulfill USP L25 requirements
- SB-803 HQ fulfills USP L37 requirements
SB-807 HQ - Column for the analysis of water-soluble ultra high molecular weight polymers
- Large particle-size gel prevents shear degradation of polymers
- Fulfills USP L38 and L39 requirements
LB-800 - Polymer-based packed columns for aqueous SEC (GFC) analysis
- Controlled column bleeding allows its use with light scattering detectors
- The eluent can be replaced with DMF enabling the analysis of polar polymer
- LB-805 (exclusion limit: about 4,000,000) newly added to the series
- Fulfills USP L38 and L39
