This document provides a technical overview of Agilent PLgel 10 µm MIXED-B columns. It demonstrates that adding extra columns can improve resolution in GPC by increasing system efficiency and decreasing the slope of the calibration curve. The PLgel 10 µm MIXED-B columns are designed for high MW polymer analysis and demanding eluent conditions. They cover a wide range of molecular weights, up to 10 million, with a linear calibration curve. These columns are particularly useful for molecular weight distributions where slightly higher than average MWs are encountered.
This document provides a technical overview of the Agilent PLgel 10 um MIXED-B columns, explaining how adding extra columns improves Gel Permeation Chromatography (GPC) resolution by increasing system efficiency and decreasing the calibration curve slope. The text demonstrates these effects using Agilent EasiCal polystyrene standards.
| Particle Size | 10 um (8-10 um range) |
|---|---|
| Molecular Weight Range | Up to 10 million |
| Column Dimensions (Single) | 300 x 7.5 mm |
| Column Dimensions (Triple) | 3x 300 x 7.5 mm |
| Part Number (Triple) | PL1110-6100 |
Resolution is improved by the addition of extra columns due to an increase in system efficiency and a decrease in the slope of the calibration curve.
The recommended conditions include using THF as the eluent, a flow rate of 1.0 mL/min, and RI detection.
