Mass Spectrometry

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.

Driving the quality and scope of pesticide residue analysis forward is a constant and global endeavor. Is it time to embrace full scan, high resolution and accurate mass?

Presenting new considerations to evaluate drinking water.

Legacy flame retardants (FRs), emerging FRs and dioxins are all infiltrating our environment. How are they linked and how should we assess their impact on human and environmental health?

Could a new nanofabricated surface lower the limit of detection – and remove the need for matrix – with existing MALDI MS instrumentation?

No confirmed sightings. No little green men. Still hope...

Hyphenated chromatography techniques enable the selection of representative biomarkers of oxidative stress – and help resolve the huge complexity of lipid oxidation products.

Are today’s ‘blue sky’ instrumental techniques tomorrow’s industry standard?
