Malvern Panalytical PS Stds Kit - Med, 0.5g x 10 Mol. Wts. TDS0005

Polystyrene (PS) molecular weight standard kit supplied for GPC/SEC calibration and detector verification. The kit contains pre-weighed bulk PS standards intended for column calibration, triple-detection calibration and verification of molecular weight determinations for synthetic polymers. Each vial provides a defined molecular weight that enables normalization, detector offset and band-broadening corrections during chromatography and light-scattering measurements.

Key Features:

• Polymer: Polystyrene (PS)
• Contents: 10 vials (1 each = 10 total)
• Mass per vial: 0.5 g
• Molecular weights (Mw) included: 3,730; 2,480; 1,230; 579; 197; 55.1; 31.4; 12.8; 3.95; 1.2 (Da × 10^0 to 10^3 as listed)
• Mw/Mn (polydispersity) values provided for each standard (approx. 1.02–1.07)

Advantages:

• Pre-weighed bulk powder standards simplify sample preparation for GPC/SEC calibration and reduce weighing variability.
• Supplied molecular weight values and narrow polydispersity support accurate column calibration, detector normalization and verification for polymer molecular-weight measurements.
• Designed for use with conventional and triple-detection (light scattering) calibration workflows to enable simultaneous corrections for normalization, offsets and band-broadening.
