Note: All calibration kits contain standards that are uniformly separated
logarithmically to give equally distributed data points on a calibration
curve over the Mp range stated in the molecular weight range column.
SHODEX CALIBRATION KITS:
When size exclusion chromatography (GPC or GFC) is performed, it is
necessary to make a calibration curve. It is recommended that Shodex
STANDARD be used to obtain the calibration curve. The molecular weight
range of Shodex STANDARD are very narrow and molecular weights are
measured accurately. Five types of standards are available.
