Data Analysis

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

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.

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

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.

How to bring better diagnostic tests to the market to benefit patients.

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 this white paper we examine the deformulation workflow, demonstrating the value of the technique of Morphologically Directed Raman Spectroscopy (MDRS) within this context. Case studies illustrate the relevance of MDRS data.

Particle agglomeration can compromise the clinical efficacy of pharmaceutical products and must therefore be closely controlled. Automated particle image analysis provides one technology which can aid agglomerate detection. This article provides practical guidance on how imaging can be applied as a routine method to robustly identify and quantify the state of agglomeration of pharmaceutical formulations.
