Online Filtration Capability

According to Dr Mark Jordi, President at Jordi Labs LLC, the online filtration capability offered by Viscotek high temperature gel permeation chromatography (HT-GPC) systems from Malvern Instruments has removed the need for dangerous and difficult manual filtration during high temperature polymer analysis.

“GPC is an integral part of Jordi Labs’ analytical capabilities,” said Dr Jordi. “The Viscotek systems provide a richness of information not obtained with other instruments. The online filter for the high temperature GPC instruments works well. We previously performed this manually and it was both dangerous and difficult. Online high temperature filtration is a big improvement.”

Dr Jordi continued; “As experts in polymer characterisation, offering over 30 years of experience in the field, Jordi Labs use Viscotek GPC systems for routine quality control, failure analysis, and product deformulation. The ability to compare polymer molecular weight, intrinsic viscosity and molecular size in a single measurement is powerful for identifying subtle differences in a polymer system. We especially like the ability to prepare and evaluate the Mark Houwink plots to compare branching in polymer systems. Two high temperature systems are also used extensively for polyethylene and polypropylene characterisation.”

Jordi Labs specialises in performing laboratory analysis using High Temperature GPC, also known as High Temperature Gel Permeation Chromatography.
