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.

This document introduces Agilent PLgel 10 µm MiniMIX-B narrow bore GPC columns, which can provide high performance comparable to our conventional ID columns, with the benefit of ~ 70 % reduction in solvent consumption, increased operator safety and reduced solvent disposal costs.

Agilent PLgel 10 µm MIXED-B columns are versatile polymethylmethacrylate standards designed for high molecular weight polymer analysis and demanding eluent conditions. The PLgel 10 µm MIXED-B spans a wide range of molecular weights, up to 10 million, with a linear calibration curve.

This document introduces the application of Agilent PLgel 10 μm MIXED-B columns in the analysis of high molecular weight polymers

This document describes a method for analyzing polybutadiene using Agilent PLgel 5 μm MIXED-D columns. The column is specifically designed for the analysis of relatively low molecular weight polybutadiene, where material above 400,000 MW is unlikely to be present. The high pore volume, concentrated in this operating range, combined with the 5 μm efficiency, provides excellent resolution for low MW polymers and oligomers.

This document introduces the technical overview of combining gel permeation chromatography (GPC) with Fourier transform infrared (FT-IR) spectroscopy. A linear concentration response is required for FT-IR to be successfully employed in GPC. The coupling of these techniques allows the composition of copolymers and blends to be investigated, providing a wealth of information.

Describes how Agilent 356-LC RI Detector can be used for fast and automated detection of epoxy resins

This document describes the advantages and characteristics of the PL-SAX 1000Å material. This material is suitable for the analysis and purification of globular proteins, with the optimum pore size for maximum loading and low band broadening. PL-SAX is a hydrophilic strong anion exchange chromatographic packing material from Varian, Inc. The combination of the rigid macroporous polystyrene/divinylbenzene (PS/DVB) polymer matrix and chemically stable quaternized polyethyleneimine coating allows the analysis of biomolecules over a wide range of mobile phase conditions and pH. The physical stability of the media permits their use with high eluent flow rates and high speed gradients for very rapid separations. This excellent stability ensures both rapid equilibration between separations and the use of aggressive clean-up procedures employing high salt, NaOH, mineral and organic acids.

This document introduces the application of the Varian Evaporative Light Scattering Detector in the GPC analysis of polymer blends (and block copolymers).

This document introduces the response characteristics of RI and ELSD, and uses a series of polystyrene standards for research. The results show that the ELSD has higher sensitivity, but the relative peak areas of the two are very similar. In addition, the ELSD performs better at low molecular weights.
