Data Analysis

GPC/SEC is mainly used for the characterization of macromolecules including synthetic and natural polymers (including polysaccharides) as well as proteins or RNA/DNA. This white paper provides an introduction to the technique in 30 minutes.

In this application note, we show that Malvern’s OmniSEC software can now communicate with Waters Empower® for the seamless exchange of sample sequences. This allows OmniSEC to follow the injections performed by a Waters SEC system and to synchronize data collection. A selection of proteins was used to demonstrate the measurement of protein molecular weight, oligomeric and aggregation state.

Four different polymers are analyzed by GPC/SEC to investigate the effect of molecular weight, dispersity and molecular structure on the final properties of the polymer.

Automated and reliable tools for spatially annotating metabolites from imaging mass spectrometry data are essential.

New developments are mobilizing Raman, mid-infrared and near-infrared spectroscopy for a whole host of innovative handheld applications.

Fingerprinting ice with FTIR spectroscopy ahead of New Horizons flyby of Pluto

And it appears Pluto loves us back – its “two-tone heart” has enchanted scientists and the general public alike. But what’s that got to do with analytical science?

This paper shows how using a solvent trap can be used to prevent sample drying/solvent loss during extended testing, helping to ensure that only rheological changes are being measured and not artifacts resulting from drying of the sample at the air/sample interface.

The top 10 reasons to consider an advanced multi-detector SEC system, which incorporates light scattering detectors for the measurement of absolute molecular weight and molecular weight distribution with excellent accuracy.

The stability of a protein sample and its tendency to aggregate is explored using a combination of SEC-MALS and DLS
