Introduces the method of using Agilent PLgel 10 µm MIXED-B columns to analyze fluoropolymers
This document provides a technical overview of the Agilent PLgel 10 um MIXED-B columns, which are designed for analyzing high molecular weight polymers under demanding eluent conditions such as fluoropolymers in dimethyl formamide. The text highlights that these columns span a wide range of molecular weights up to 10 million with a linear calibration curve.
| Particle Size | 10 um |
|---|---|
| Molecular Weight Range | up to 10 million |
| Column Dimensions | 300 x 7.5 mm |
| Eluent | DMF (0.1% LiBr) |
| Flow Rate | 1.0 mL/min |
| Temperature | 70°C |
| Detection Method | RI |
It is necessary to reverse the electrical polarity of the RI detector signal in order to obtain a positive peak.
The recommended conditions include using DMF (0.1% LiBr) as eluent at a flow rate of 1.0 mL/min and a temperature of 70°C.
