Calibration Standards for Organic SEC (GPC)
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.
Please refer to Calibration Standards for Aqueous SEC (GFC)
