Product information

 

Shodex STANDARD P-82 and STD P-series is a calibration standard for aqueous size exclusion chromatography.

Pullulan is a polysaccharide, units of maltotriose are connected with α-1,6 bond, and its chains are linear without branched chains.

The sample solution of this standard is easy to prepare and easy to handle, because it is stable without agglomeration, crystallization or electrical charge, and moreover pullulan is not adsorbed to column packing materials. This is useful as molecular weight standard for Size Exclusion Chromatography (SEC).

  • For aqueous SEC (GFC)

  • Unbranched pullulan standard

  • High solubility in water eliminates the possibility of recrystallization

​​

In order to obtain a calibration curve, plot Mp and retention time using the same analysis condition as the target sample analysis. Relative molecular weight of unknown sample can be calculated by comparing the calibration curve with the measured results.


Pullulan kit: STANDARD P-82 (8 vials)

STANDARD P-82 kit consists of 8 kinds of different molecular weight standards of 200 mg each.

​​

Pullulan single type: STD P-series (1 vial)

STD P‑series consists of a single standard with 500 mg (8 different kinds available).

​​

Note: Molecular weights (Mp, Mw/Mn) of a standard kit or each single type may vary depending on production lots. Always refer to the inspection certificate.
