This document presents a repeatability study of polypropylene analysis using Agilent PLgel MIXED-B columns and the Agilent PL-GPC 220 integrated, high temperature instrument. The system's ability is demonstrated through the analysis of six polypropylene injections. A commercial sample of polypropylene was prepared at 1.5 mg/mL using the PL-SP 260 sample preparation system with a dissolution temperature of 160 °C and a dissolution time of two hours. Six aliquots of the master batch solution were dispensed into the PL-GPC 220 autosampler vials and placed in the carousel where the hot zone temperature was 160 °C and the warm zone was 80 °C. Figure 1 shows an overlay of the raw data chromatograms obtained for the six consecutive injections of the sample. The data were analyzed against a polystyrene standards calibration using the provided Mark-Houwink parameters to obtain the polypropylene equivalent molecular weight averages shown in Table 1.

This document provides an overview of preparative gel permeation chromatography, which improves the resolution of sample components by recycling the sample back through the column multiple times before fraction collection, thus conveniently minimizing cross-fraction contamination. The high column volume of the Agilent PLgel 10 µm 100 Å, 25 × 300 mm prep column facilitates recycle capability. Improved resolution after three cycles is observed.

Describes the importance of loading in preparative gel permeation chromatography (GPC) and how loading can be significantly increased for very low molecular weight materials such as epoxy resins.

This document introduces the application of Agilent MIXED gel technology in gel permeation chromatography and size exclusion chromatography columns. This technology allows different pore size gels to be blended together to create a column with a linear calibration suitable for a specific molecular weight range. Selectivity in GPC/SEC separations can be controlled by adjusting the column length and the pore size distribution of the packing material. Compared to individual pore size gels, MIXED gel packing provides a larger molecular weight range and better separation performance.
