enclosed Certificate of Analysis (CoA) are matching and correct.
1. Introduction
Thank you for purchasing the Shodex™ product. Shodex
OHpak
SB-2000 series is a size exclusion
chromatography column used with aqueous solvents. The column series is suitable for the preparations of
various water-soluble high molecular weight polymers, proteins, and/or oligomers, and molecular weight
distribution analysis of high molecular weight polymers. The columns with different exclusion limits are available.
Please select columns with target molecular weight ranges (see below) that meet the molecular weight range
of your samples.
