應用

Polystyrene (Broad molecular mass distribution) standard reference material is primarily intended to calibrate and evaluate the performance of instruments used in the determination of molar mass and molar mass distribution.

特點和優勢

• Available with a certificate documenting NIST-certified value for mass-average molar mass (Mw) is based on original results from light scattering and ultracentrifugation measurements.
• The certified values have metrological traceability to the SI derived unit for intrinsic viscosity (expressed as milliliters per gram).
• The NIST certificate is provided with expiration certificate, storage, handling, and maintenance instructions.

其他說明

Please download a current certificate at nist.gov/SRM for current analytes and certified values.
