Size Exclusion Chromatography (SEC)

Earlier this year I highlighted the different types of GPC/SEC standards available and where to find them on our eStore. In this post, I’m going to share some tips and tricks about preparing your standards and making them last. But…READ MORE >

On November 2nd, Waters and Malvern Panalytical is co-hosting a webinar: “Unlocking Polymers in Medical Devices: Combining High-Resolution Separations from the Waters ACQUITY APC and Advanced Detectors from the Malvern Panalytical OMNISEC REVEAL“ co-presented by Larry Meeker (Waters, Application Scientist)…READ MORE >

I spill a lot of digital ink extolling the virtues of our OMNISEC system, and for good reason!  The power of a complete, advanced detection SEC system is undeniable.  But in this post, I’m going to focus on a single,…READ MORE >

If only I asked an expert earlier… Sometime before I joined Malvern Panalytical, my Gel Permeation Chromatography (GPC) knowledge level was quite low. When I was using a GPC system to analyze the polymers, synthesizing it wasn’t a cerebral process….READ MORE >

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 >

Advances in recombinant DNA technology, genomics, and immunology have greatly influenced the vaccine development process. The genetic manipulation of viruses makes them suitable as vectors for gene delivery, providing a novel and unique opportunity for vaccine design. Viruses survive and…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 >
