Calibration Standards
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.
