|Combined Use of Rheometry and GPC/SEC for Characterising Ionic Polysaccharides|
John Duffy, Bernd Schaefer, Bert Postma
This poster shows how Rheometry and GPC can be complementary tools for characterising the behaviour of polysaccharides in solution
|An Alternative to Direct Probe: Pyroprobe Coupled to High Resolution Time-of-Flight Mass Spectrometry|
Jonathan D. Byer, Joe Binkley, Karen Sam, Jeff Patrick
Direct Pyroprobe is not a substitute for direct probe, but there is some overlap, as well as additional functionality. Direct probes coupled to LECO Pegasus instruments provide unique features:
– Time-of-flight mass spectra which shows little-to-no spectral skewing
– Automatic peak finding and spectral deconvolution for better identification
– Pegasus HT has a very low maintenance source which is beneficial for direct analysis techniques
|A Reduced Workflow Solution for the Analysis of Gamma-Hydroxybutyrate (GHB) in Human Hair Samples Via an Automated Bead Mill as a Precursor to GCxGC-TOFMS and GC-HRT|

- The Biotage Bead Ruptor 24 was effective in pre-treating hair samples prior to the extraction procedure.
- The enhanced chromatographic resolution of GCxGC-TOFMS and high resolving power of GC-HRT minimized interferences and facilitated accurate analysis of GHB in hair.

In order to identify and quantify isomeric compounds independently in real-time, we introduce a novel approach where we integrate a fast GC column (“fastGC”) into a PTR-QiTOF instrument. The outstanding sensitivity of the new PTR-QiTOF (up to 4,700 cps/ppbv) is crucial for applications where time per analysis is limited, e.g. nosespace in food and flavor research. Particularly, in these fields the chemical environment is normally very complex so that a high selectivity is essential as well.
|Capillary Electrophoresis Coupled with Micro Free Flow Electrophoresis for High Speed Two Dimensional Separations of Biological Samples|
Alexander C. Johnson, Michael T. Bowser
We propose using micro free flow electrophoresis (µFFE) as a solution to the under sampling problem.
|Analysis of Polymers, Additives and Contaminates in Medical Devices using Pyrolysis-GCMS|
Pyrolysis GC-MS is a standard technique used to analyze industrial polymers. This poster will show the use of multiple temperature ramps to analyze for additives and contaminants, in addition to polymer identification, in several medical devices.
|An investigation into the effects of aging on automotive bumper samples by xylene soluble flow injection polymer analysis (XS-FIPA)|
Bassem Sabagh, Wei Sen Wong, Bernd Tartsch
This poster describes the use of flow injection polymer analysis (FIPA) as an analytical tool for xylene soluble (XS) determination with quick and easy simultaneous measurements of molecular weight (MW), intrinsic viscosity (IV) and XS%. The technique was applied to automotive bumper samples which had undergone an aging test. The results from the XS-FIPA technique highlight the differences caused by the aging process.
|DHPLC Technology as a High-throughput Detection of Mutations in a Durum Wheat TILLING Population|
