Malvern Panalytical Pullulan/Dextran Standards for LS/TD TDS3030

Malvern Panalytical Pullulan/Dextran Standards TDS3030 are pre‑weighed polymer standards supplied for light scattering / triple detection (LS/TD) calibration and verification of GPC/SEC systems. The kit provides narrow pullulan standards together with broad dextran verification standards to characterize detector responses, calculate normalization factors, detector offsets and band broadening corrections, and support absolute molecular weight measurement for water‑soluble polymer analyses.

Key Features:

• Manufacturer: Malvern Panalytical; Model: TDS3030
• Polymer types: Pullulan (narrow calibration) and Dextran (broad verification)
• Format: Pre‑weighed standards (mixed sets); 6 of each = 12 vials total
• Calibration application: Light scattering / triple detection (LS/TD) calibration and verification
• Molecular weight ranges: Pullulan narrow standards spanning ~5 kDa (and higher fractions up to 40–112 kDa per set); Dextran verification in the 50–100 kDa region
• Intended for aqueous or specified mobile phases (e.g., 5% acetic acid in water, DMSO) as indicated for pullulan/dextran use

Advantages:

• Enables characterization of detector responses and calculation of normalization factors and detector offsets for accurate absolute molecular weight measurement
• Pre‑weighed vials simplify preparation and produce reproducible standard concentrations when dissolved as instructed
• Includes both narrow calibration (pullulan) and broad verification (dextran) materials to support comprehensive calibration and verification workflows
• Reduces calibration time by allowing simultaneous calculation of normalization, offsets and band broadening corrections during triple detection calibration
