This document introduces the Agilent PL-SP 260VS sample preparation system, which is designed for manual dissolution and filtration of samples prior to gel permeation chromatography (GPC) analysis. The instrument has a temperature range of 30 to 260°C and user-selectable agitation speeds of 85 to 230 rpm, making it ideal for a wide range of polymer types, including the most difficult of samples.
The Agilent PL-SP 260VS is a sample preparation system designed for the manual dissolution and filtration of samples prior to analysis by gel permeation chromatography (GPC). It combines controlled heating across a temperature range of 30 to 260 °C with gentle agitation, selectable from 85 to 230 rpm.
The system allows for the dissolution and filtration of samples at temperatures up to 260 °C using a heater/shaker unit. Filtration is achieved using a unique hand-held pipettor with filter magazines containing stainless steel frits or glass fiber filters, specifically suited for removing fine, insoluble particulates such as carbon black from high molecular weight polymers.
