Malvern Omnisec CHR600 + CHR7100 Resolve & Reveal GPC/SEC System

• Polymer characterisation in research and development laboratories.
• Quality control of polymers in various industries, including plastics, coatings, and pharmaceuticals.
• Analysis of molecular weight distribution and intrinsic viscosity of macromolecules.
• Investigation of polymer degradation and branching.

Typical capacity

For this class of equipment, sample throughput can vary, but multi-sample automated analysis is common.

Power supply

Units of this type commonly require a standard laboratory power supply, typically 230V, 50Hz in the UK.

Footprint

A system comprising a CHR600 and CHR7100 would typically require significant bench space, often around 60-80 cm width and 50-70 cm depth per module.

Detection capabilities

The Resolve detector commonly includes refractive index (RI), light scattering (LS), and UV detectors for comprehensive polymer characterisation.

Solvent compatibility

Systems are typically compatible with a range of organic solvents suitable for GPC/SEC applications.

Operating temperature range

Integrated column ovens commonly offer temperature control from ambient to typically 80°C or higher.

• What is GPC/SEC used for?

  Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC) is a technique used to determine the molecular weight distribution, molecular size, and intrinsic viscosity of polymers and macromolecules.

• What is the 'Resolve' detector?

• Is this system suitable for aqueous samples?

• What level of maintenance is typically required?

• Can this system be upgraded?

Chromatography systems command strong respect within analytical and pharmaceutical sectors. Buyers typically prioritise equipment with verified maintenance records and clear calibration history, as these directly affect analytical accuracy. Used units from established manufacturers remain highly valued for their reliability. Key strengths include reproducible results, robust construction, and established spare parts availability. Industry sentiment reflects confidence in these systems when sourced from reputable suppliers with transparent service documentation.
