One of the pleasures of working in the Applications Lab is that I get to analyze a variety of GPC/SEC sample types.  I can be finishing up a set of biodegradable polyesters, currently running low molecular weight oligomers, while getting…READ MORE >

In a previous post, I described how the composition of a sample can be determined through GPC/SEC analysis. This powerful method has found many applications, with a recent example being AAV characterization. With these types of analyses becoming increasingly popular,…READ MORE >

A few days ago, my colleague Dr. John Stenson previewed the upcoming launch of the OMNISEC software’s newest feature: compositional analysis!  Amidst your excitement at the great content headed your way, you might be wondering, “what can compositional analysis do…READ MORE >

I always find it incredibly exciting to talk about new features and functionality that we have created for our systems… and this time is no different! I understand that systems need to be continually improved and expanded to meet our…READ MORE >

In my last post, I highlighted the most common GPC/SEC columns available from the Malvern Panalytical eStore.  Just like with columns, scientists rely on the selection of appropriate GPC/SEC standards to generate reliable methods and obtain quality results.  In order…READ MORE >

Columns and standards are an essential part of every GPC/SEC analysis.  To obtain quality data, scientists depend on the selection of appropriate columns and standards specific to their application.  In order to accommodate a diverse range of applications, Malvern Panalytical…READ MORE >

Last year I highlighted a handful of publications featuring OMNISEC as a powerful analytical tool for multi-detector GPC/SEC analyses.  As time marches on, even in these unprecedented times, OMNISEC continues to become more pervasive in the global scientific community.  Therefore,…READ MORE >

When you think of gel permeation chromatography / size exclusion chromatography (GPC/SEC) you probably associate the technique with the analysis of macromolecules such as proteins and polymers.  After all, that’s what it does best!  However, as researchers and manufacturers push…READ MORE >

Earlier this year we released the OMNISEC v11.20 software.  This latest iteration expands OMNISEC’s capabilities to include conventional and universal calibration analysis methods.  Since the data available from these methods based on calibration curves may seem similar to information from…READ MORE >
