Providing simultaneous measurement of molecular weight, intrinsic viscosity, and hydrodynamic radius in only 12 minutes, this technique minimises the exposure of operators to solvent
A new application report is available from Viscotek Europe describing a fast, precise, and accurate analytical methodology for process quality control of polyesters.
The report discusses how Viscotek's Flow Injection Polymer Analysis (Fipa) technique is particularly well suited to the quality control of polyesters such as polyethylene teraphthalate (PET) that require dissolution in expensive and hazardous solvents such as hexafluoroisopropanol (HFIP).
Providing simultaneous measurement of molecular weight, intrinsic viscosity, and hydrodynamic radius in only 12 minutes, the FIPA technique minimises the exposure of operators to the hazardous solvent.
Due to the short analysis time it is also possible to make significant savings in HFIP costs and give fast feedback to the PET production plant about the results obtained.
The new technique is shown to be a valuable high productivity replacement for the traditional Ubbelohde measurement method that is slow and labour intensive.
Using Viscotek's OmniSec software, the Fipa technique may also be used to determine additional useful information on percentage polymer (without knowing exact concentrations) and branching.
