Introduces the characteristics and advantages of Agilent PL aquagel-OH 50 8 μm column for the separation of water-soluble polymers.

This document provides a technical overview of Agilent PL aquagel-OH 40 8 µm columns, which are suitable for determining the molecular weight distributions of water-soluble polymers and for separating oligomers and small molecules. These columns have an extremely hydrophilic and neutral surface, allowing for high-performance analysis of analytes with neutral, ionic, and hydrophobic moieties. The PL aquagel-OH 40 8 µm high-performance columns are ideal for medium molecular weight separations, offering high pore volume and high column efficiency.

This document describes the features and characteristics of Agilent PL aquagel-OH 40 8 μm high performance columns, which are ideal for medium molecular weight separations of polysaccharides. They combine high pore volume and high column efficiency for maximum resolution.

This document introduces the application of PL aquagel-OH 60 8 μm and PL aquagel-OH 40 8 μm high performance columns for relatively high molecular weight aqueous separations of methyl cellulose by size exclusion chromatography (SEC).

This document introduces the Agilent PL aquagel-OH MIXED-H 8 μm columns, which provide high resolution (>35,000 plates/m) over a very wide range of molecular weights, simplifying column selection and providing a flexible analytical system. Due to the extremely hydrophilic nature of these columns, neutral polymers such as polyethylene glycol/oxide (PEG/PEO) can be run with pure water as the eluent, using size exclusion chromatography (SEC). Figure 1 shows a typical raw data chromatogram for a mixture of Agilent PEO/PEG standards. The broad molecular weight resolving range of the PL aquagel-OH MIXED-H 8 μm column is clearly evident.

This document describes the features of Agilent PL aquagel-OH 30 8 μm high performance columns. The columns are highly hydrophilic and suitable for separations using water as the solvent. PL aquagel-OH columns are ideal for low molecular weight separations by size exclusion chromatography, offering high pore volume and high column efficiency.

This document introduces the features and characteristics of Agilent OligoPore Columns (THF), including column design, use methods, performance advantages, etc.

This document introduces the simple calibration method of Agilent OligoPore Columns (DMF), using the integrated Agilent PL-GPC 220 GPC/SEC system, using Agilent polyethylene glycol (PEG) narrow standards at 80 °C

This document introduces the simple calibration method of Agilent OligoPore columns. OligoPore columns utilize an innovative medium that exhibits significantly increased pore volumes compared to conventional low pore size columns, resulting in higher resolution in the oligomeric region. OligoPore columns are specifically designed for the analysis and fingerprinting of oligomeric distributions. The composition of Agilent PMMA and PS molecular weight standards and how to characterize the low molecular weight region of OligoPore calibration through calibration are also described in this document.

Agilent PLgel MiniMIX Columns Technical Overview, introduces the features of Agilent PLgel MiniMIX Columns, including high performance, excellent solvent compatibility and mechanical stability, as well as reduced solvent consumption, increased operator safety and reduced solvent disposal costs.

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.
