This polystyrene standard with a nominal molecular weight of 500 Daltons delivers reliable, reproducible performance for gel permeation chromatography and size exclusion chromatography applications. Designed to support precise calibration and molecular weight determination, it is highly suited for use in analytical workflows assessing low molecular weight polymer samples. Researchers in polymer science, materials characterization, and quality control benefit from its well-defined molecular characteristics, making it ideal for comparative analyses, method validation, and instrument qualification.

This standard dissolves readily in common organic GPC solvents, including tetrahydrofuran, toluene, and chloroform, ensuring versatility in various laboratory protocols. It is compatible with Agilent GPC and SEC systems, including InfinityLab and PL series instruments, as well as other major chromatography platforms. The product is also suitable for multi-detector GPC methods, such as those utilizing refractive index, light scattering, or viscometry detectors.

To achieve optimal calibration accuracy across a broad molecular weight range, this standard can be used in conjunction with higher molecular weight reference materials from the same product line. Packaged to maintain integrity and purity, it supports high-quality data generation for routine analysis and method development in research and industrial laboratories.
