Malvern Panalytical PMMA STDS Kit, 0.5g x 7 Mol. Wts. TDS0007

PMMA Stds Kit is a set of polymer calibration standards for molecular-weight calibration and verification in chromatographic and light-scattering applications. The kit contains seven pre-weighed PMMA standards (0.5 g each) spanning a broad molar-mass range, and is intended for use to calibrate methods and detectors and to verify newly created methods in size-exclusion chromatography / GPC and light scattering workflows. Storage and handling guidance for standards notes they should be kept dry and out of direct sunlight for stability.

Key Features:

• Polymer: PMMA (polymethyl methacrylate)
• Quantity: 7 vials, 0.5 g per vial
• Molar masses (Mw, kDa): 955, 509, 202, 63, 20.3, 6.83, 2.89
• Reported Mw/Mn values: 1.05, 1.03, 1.02, 1.02, 1.03, 1.10, 1.10
• Intended application: calibration and verification for light scattering and chromatographic molecular-weight measurements

Advantages:

• Provides a broad molar-mass range across seven standards for comprehensive calibration and method verification
• Pre-weighed 0.5 g vials simplify preparation and ensure consistent reference material amounts
• Suitable for use in light scattering workflows to calibrate methods and detectors
• Standards are stable when kept dry and out of direct sunlight (stability guidance provided)
