Agilent offers a calibrated polystyrene (PS) polymer standard with a nominal molecular weight of 20000 Daltons, designed to support precise molecular weight determination in macromolecular analysis. This product enables highly reproducible calibration for size exclusion chromatography SEC and gel permeation chromatography GPC methods, ensuring reliable and accurate performance of analytical systems. The polymer exhibits a narrow molecular weight distribution, making it ideal for detailed molecular weight profiling and quality control applications across polymer, material science, and chemical research laboratories.

This polystyrene standard is compatible with a variety of chromatographic instruments, particularly those equipped with refractive index, light scattering, or UV detectors. It integrates seamlessly with Agilent SEC and GPC columns including PLgel and InfinityLab series and can also be used with third-party systems designed for polymer characterization. Researchers leverage this standard in the calibration of GPC and SEC methods, instrument validation, and the development of polymer analysis protocols. The consistent quality and well-defined molecular properties makes it suitable for use in fundamental research, process monitoring, and comparative studies across industrial and academic environments. Each batch is rigorously tested to guarantee batch-to-batch consistency for dependable results.
