A GPC/SEC system contains a lot of parts!  In addition to columns and standards, there are a number of consumable items required to actually use the instrument.  Since I didn’t get to them in my last post, this one will…READ MORE >

I began this post with the intention of discussing the most popular GPC/SEC consumables available from the Malvern Panalytical eStore.  As with my previous posts on columns and standards, my goal was to provide a list of consumables to keep…READ MORE >

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 you can determine the composition of a sample 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 >

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 >
