Malvern Panalytical A4000, Aqueous GPC/SEC Column 300x8m CLM3018

A4000, Aqueous GPC/SEC Column CLM3018 is a 300 mm x 8.0 mm polymethyl‑methacrylate (A‑series) chromatography column designed for aqueous gel permeation/size‑exclusion chromatography of water‑soluble polymers. It provides separation for high molecular weight species—specified with an exclusion limit of 1,000,000 Da (Pullulan)—and is intended for use with aqueous buffers and organic modifiers such as acetonitrile, methanol, DMF and DMSO.

Key Features:

• Column dimensions: 300 mm x 8.0 mm
• Column type: Polymethyl‑methacrylate (A‑series)
• Exclusion limit: 1,000,000 Da (Pullulan)
• Particle size / column efficiency: 10 µm; theoretical plate number >16,000 (per column)
• Maximum operating pressure: 3.0 MPa
• Shipping solvent: Water
• Compatible mobile phases: Aqueous buffers with organic modifiers (acetonitrile, methanol, DMF, DMSO)

Advantages:

• Specifically optimized for aqueous GPC/SEC separations of water‑soluble polymers, enabling reliable high‑molecular‑weight analysis.
• High column efficiency (>16,000 plates) and 10 µm media deliver sharp, reproducible separations.
• Robust performance at moderate pressures (up to 3.0 MPa) with water as the shipping solvent simplifies handling and startup.
• Broad solvent compatibility with common aqueous buffers and polar organic modifiers supports flexible method development.
