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

Read how DLS-based optical microrheology can be used to determine the rheological behavior of polymer solutions and the impact of tracer particle chemistry on the measured microrheological response.

Monika Dittman (Agilent Technologies) and Fabrice Gritti (Waters) offer a manufacturer point of view on the practical limits of LC.

The evidence contradicts those who say liquid chromatography has fully matured.

What drives someone to throw aside selfish pursuits to focus on projects with true philanthropic impact? Here, the winners of the 2015 Humanity in Science Award provide their answers.

At ASMS 2015, GC-Orbitrap™ technology was unleashed onto an expectant analytical community. Here’s the backstory.

Raman spectroscopy has evolved into a powerful characterization technique for many applications. What more needs to be done to make it effective in clinical analysis?

The 2014 Nobel Prize in Physics, awarded “for the invention of efficient blue light-emitting diodes,” has put LEDs under the spotlight, particularly as a stable, robust and efficient light source in analytical sciences.

In this application note, we'll describe the successful molecular weight measurement of a polystyrene, PMMA and PVC sample using the OMNISEC system. This instrument can accurately measure the absolute molecular weight of any polymers independent of elution volume or structure. Although the measurements here have been performed using simple polymers, these methods can be applied to any polymer measured by GPC.

In the quest for increased sensitivity or higher resolution, let’s not lose sight of our objectives.
