Polystyrene Standard 8,400,000 | GPC/SEC Calibration
The Polystyrene Standard 8,400,000 is a single-point Gel Permeation Chromatography (GPC) calibration standard designed for high-molecular-weight characterization and confirmation. With a molecular weight of 8.4 million Daltons, this standard is ideal for labs conducting size-based separation of large polymeric compounds and biomolecules. It is widely used in research, manufacturing, and quality assurance environments where precise molecular weight determination is critical.
This solid-form calibration material delivers excellent reproducibility across a variety of detection methods, including Refractive Index (RI), Evaporative Light Scattering Detection (ELSD), and UV detection. It supports LC-based GPC/SEC workflows and is shipped under ambient conditions. Upon reconstitution, the shelf life is approximately 1 week, with a sealed shelf life of up to 36 months when stored at 4°C.
Waters' Polystyrene Standards are trusted for their high purity and batch-to-batch consistency, providing scientists with reliable reference points for retention time and system suitability. When used as part of a robust calibration protocol, this standard ensures data integrity for polymer size distribution, average molecular weights (Mn, Mw), and resolution checks.
