This document introduces the application of polystyrene and polyethylene standards in trichlorobenzene (TCB) in gel permeation chromatography (GPC).
This document provides a technical comparison between polystyrene and polyethylene narrow standards used in high-temperature conventional Gel Permeation Chromatography (GPC) with Trichlorobenzene (TCB). It details the generation of retention time and molecular weight calibration curves, noting that while polystyrene standards yield linear results up to 7 million daltons, polyethylene standards show non-linear behavior at low molecular weights.
The calibration curves are generated at 160 °C.
The polystyrene narrow standards have Mp values up to 7 million daltons.
