Malvern Panalytical A7000, Aqueous GPC/SEC Column 300x8m CLM3022

Aqueous GPC/SEC Column A7000 (CLM3022) is a 300 mm x 8.0 mm polymethyl‑methacrylate column designed for size‑exclusion chromatography of water‑soluble polymers. It is shipped in water and is compatible with aqueous buffers containing organic modifiers such as acetonitrile, methanol, DMF and DMSO. Typical use cases include molecular weight distribution and separation of very high molecular weight water‑soluble polymers using GPC/SEC instrumentation.

Key Features:

• Dimensions: 300 mm x 8.0 mm
• Column chemistry: Polymethyl‑methacrylate (A‑series)
• Exclusion limit (Pullulan): 500,000,000 Da (A7000)
• Shipping solvent: Water
• Compatible solvents: Aqueous buffers with organic modifiers (e.g., acetonitrile, methanol, DMF, DMSO)
• Column packing/particle descriptor: listed as A7000 (table entry CLM3022) with associated column performance parameters

Advantages:

• Enables separation and characterisation of very high molecular weight water‑soluble polymers due to a very high exclusion limit.
• Supplied in a 300 x 8.0 mm format compatible with standard GPC/SEC systems for routine polymer analysis.
• Compatibility with aqueous buffers and common organic modifiers provides flexibility for a range of solvent conditions and sample types.
