Malvern Panalytical TDS Polystyrenes Standards N+B TDS3000

TDS Polystyrenes Standards N+B TDS3000 is a pre-weighed polystyrene standards kit for triple-detection size-exclusion chromatography calibration and verification. The kit contains both narrow and broad distribution polystyrene standards supplied in individual vials for straightforward “just add solvent” preparation. It is intended for use in light-scattering/viscometry detector normalization, inter-detector delay and band-broadening calibration, and verification of chromatographic system performance in organic solvent applications.

Key Features:

• Polymer: Polystyrene
• Distribution: Narrow + Broad (N+B)
• Contents: 6 narrow vials + 6 broad vials = 12 total pre-weighed vials
• Approx. mass per narrow vial: 10 mg
• Narrow standard approximate Mw: 90–105 kDa
• Broad verification approximate Mw range: 235–280 kDa
• Designed for triple-detection (MALS/Viscometer/RI) calibration and verification

Advantages:

• Pre-weighed, single-use vials reduce sample preparation time and eliminate weighing variability
• Includes both narrow and broad standards enabling one-step calibration and subsequent verification of detector response and chromatographic method
• Standards supplied at molecular weights appropriate for light-scattering normalization and verification across typical organic SEC measurement ranges
