Refurbished Viscotek 270 Dual Detector – GPC/SEC Dual Detector System for Polymer Analysis

The Viscotek 270 Dual Detector is an advanced analytical instrument designed for gel permeation chromatography (GPC) and size exclusion chromatography (SEC) applications. It provides dual detection capabilities, allowing accurate analysis of polymer properties such as molecular weight and intrinsic viscosity.

This detector is widely used in polymer research, chemical laboratories, and material science applications.

The Viscotek 270 integrates dual detection technology, typically combining refractive index (RI) detection with viscometry. This allows simultaneous measurement of concentration and molecular structure, delivering comprehensive polymer characterization.

It is designed for seamless integration into GPC/SEC systems and supports high precision analytical workflows.

Working Principle

The system operates by passing the sample through two detection systems:

• Refractive Index (RI) detector measures concentration
• Viscometer detector measures intrinsic viscosity

Working steps:

• Sample enters detector after column separation
• RI detector measures concentration changes
• Viscometer measures flow resistance
• Data is combined for molecular weight calculation

This dual detection provides more accurate and detailed analysis compared to single detectors.
