Malvern Panalytical TDS Polyethylene Oxide Standards N+B TDS3010

TDS3010 Polyethylene Oxide Standards N+B is a pre‑weighed calibration kit of polyethylene oxide (PEO) polymer standards provided by the manufacturer for gel permeation/size‑exclusion chromatography and light‑scattering calibration. The kit contains narrow and broad PEO standards intended for method calibration and verification in aqueous mobile phases; standards are supplied as pre‑weighed vials that dissolve to produce the recommended solution concentration when 10 mL of mobile phase is added and left to dissolve. These standards are intended for use in molecular‑weight calibration, detector calibration and method verification for aqueous polymer separations.

Key Features:

• Manufacturer part designation: TDS3010
• Polymer: Polyethylene oxide (PEO)
• Kit type: Narrow + Broad (calibration and verification)
• Number of vials: 6 of each = 12 total
• Approx. mass per vial: 14 mg
• Approximate Mw range for narrow standard: 19–22 kDa
• Preparation: pre‑weighed vials dissolve to ~1–2 mg/mL when diluted with 10 mL mobile phase

Advantages:

• Pre‑weighed, ready‑to‑prepare vials simplify standard preparation and ensure consistent concentration.
• Includes both narrow and broad distributions enabling detector calibration and subsequent method verification.
• Formulated for aqueous mobile phases and suitable for light‑scattering and conventional/ universal calibration workflows.
• Supplied masses and Mw values support reproducible molecular‑weight calibration and method comparability.
