Intertek uses a GPC system where the entire GPC system is held at elevated temperature to ensure no part of the sample can re-precipitate before or during analysis leading to erroneous results. HTGPC allows the measurement of average molecular weights and molecular weight distributions of polymers that will not dissolve in GPC solvents at convention GPC temperatures.
Types of polymer which may be characterised with HTGPC:
Polyethylene and polypropylene which can only be analysed by HTGPC, along with other polymers, can be analysed in trichlorobenzene as listed below.
Polymers amenable to HTGPC analysis in Trichlorobenzene at elevated temperature include:
Conventional or Universal calibration:
GPC analysis can be performed using conventional calibration against polystyrene polymer standards to give polystyrene equivalent molecular weights. Polyethylene and polypropylene may be analysed by universal calibration which provides absolute molecular weights. For the latter the sample needs to be pure homopolymer.
