Chromatography applications expert Wei
Sen Wong from Malvern Instruments, will talk about the practicalities of
high temperature gel permeation chromatography (HT-GPC) at the Society of
Plastics Engineers (SPE) Joint International Polyolefins/FlexPack Conference
being held in Houston, Texas, February 26-29, 2012. Malvern Instruments is also
an exhibitor at the event and will display their systems at Booth #40.
Wei Sen Wong's presentation on the
‘Application of high temperature chromatographic and viscometric techniques for
the characterization of polyolefins', focuses on the unique challenges of using
advanced detectors, such as static light scattering (SLS) and viscometry, when
characterizing polyolefins with gel permeation chromatography at elevated and
high temperatures. It also highlights the excellent results that are possible
using HT-GPC systems for a number of polyolefin samples.
Malvern's Viscotek HT-GPC system brings
full automation to high temperature analysis. Requiring no user interventions
for sample filtering, it is uniquely specified for safe, routine operation at
the high temperatures (160
oC) necessary for analyzing polyethylene
and polypropylene. It measures absolute molecular weight, molecular weight
distribution, and polymer chain branching in just a single experiment. These
are critical parameters for polyolefins that influence in-use properties such
as strength and perme ability.
