Agilent’s polystyrene standard with an approximate molecular weight of 4000 Da is designed for precise molecular weight calibration in gel permeation chromatography (GPC) and size exclusion chromatography (SEC) applications. This high-purity standard allows for accurate calibration curves, ensuring reliable and reproducible results in polymer analysis. It is particularly suited for laboratories working on polymer characterization, quality control, and research where precise determination of molecular weight distribution is critical.

This standard is compatible with Agilent GPC/SEC instruments and often used in conjunction with Agilent’s comprehensive range of calibration standards and columns, including PLgel and InfinityLab lines. Researchers in materials science, chemical engineering, and polymer chemistry utilize this product to benchmark and validate instrument performance, optimize separation conditions, or compare unknown samples to a known reference. The material is supplied with a certificate of analysis, detailing its molecular weight and dispersity, providing confidence in traceability and analytical rigor. Its narrow distribution and defined characteristics make it an ideal choice for quantifying low molecular weight polymers, optimizing analytical protocols, and supporting regulatory or validation requirements across various GPC and SEC workflows.
