This document is about Agilent PLgel MIXED Columns technical overview

This document introduces the features and advantages of the Agilent PLgel MIXED-C columns, including a linear calibration range of up to 2 million MW, high resolution, rapid solvent exchange capability, excellent temperature stability, and high resolution. The advantage of choosing the appropriate sample concentration is demonstrated by analyzing a broad polystyrene sample.

Agilent PLgel 10 µm MIXED-B columns are designed for high MW polymer analysis and demanding eluent conditions. The columns cover a wide range of molecular weights, up to 10 million, with a linear calibration curve. It is particularly useful for molecular weight distributions where slightly higher than average MWs are encountered. The 8–10 µm particle size provides good resolution with relatively low pressures for enhanced lifetimes in demanding conditions.

This document introduces the features and characteristics of Agilent PLgel Columns, including high pore volume, high efficiency, wide solvent compatibility and outstanding physical rigidity.

Narrow bore GPC columns from Polymer Laboratories, now a part of Varian, Inc., offer high performance, excellent solvent compatibility and mechanical stability. These columns can be used with conventional GPC equipment and provide high performance, comparable to PL’s conventional ID columns, the benefit of ~ 70 % reduction in solvent consumption, increased operator safety and reduced solvent disposal costs.

The document introduces Agilent PLgel Individual Pore Size Columns, a high resolution GPC column that offers high resolution over a specific molecular weight range. The document also provides PLgel individual pore size columns polystyrene molecular weight calibration curves that can be used to determine the molecular weight range over which optimum resolution will be achieved.

This document describes the linear calibration curves for Agilent PLgel MIXED columns. These columns use a mixture of pore size materials to cover a broad range of molecular weight and eliminate column mismatch through linear calibration.

This document introduces the features and performance of PLgel columns, including high pore volume and efficiency, wide solvent compatibility and excellent physical rigidity.

This document introduces the relationship between column efficiency and solvent transfer for Agilent PLgel columns.

The PLgel individual pore size GPC columns offer high resolution over a specific molecular weight range.

This document introduces the matching relationship between Agilent PLgel Individual Pore Size Columns and solvent. It introduces the characteristics of polystyrene standard and the elution curves under different solvent conditions.

Agilent EasiCal Pre-prepared Calibration Kits Technical Overview

EasiCal PS-1 pre-prepared standards can be used to calibrate Agilent PLgel 10 µm MIXED-B columns. All of the standards are resolved as the column exhibits a linear calibration over the full range of molecular weight covered.

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.
