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 >

It’s September again, and that means it’s back-to-school time!  However, things will inevitably look a little different this year with the prevalence of remote learning and virtual classes.  While we lament our inability to meet face-to-face, at Malvern Panalytical we’re…READ MORE >

Back in June we released the OMNISEC v11.20 software that included column calibration methods.  In a previous post, I summarized how the methods with calibration curves work and what information they offer. This post will offer some tips for setting…READ MORE >

Are you generating Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC) data for comparison to historical results?  Do your novel samples complicate multi-detector analyses?  Or are you simply feeling nostalgic for calibration curves?  Whatever your reason, the OMNISEC software now offers a…READ MORE >

Whether you’re characterizing a one-of-a-kind sample or performing routine analysis on established products, the accuracy of your multi-detector GPC/SEC data relies on your dn/dc value. Fortunately, the OMNISEC system and its OMNISEC software offer different ways to determine and implement…READ MORE >

Do you want an OMNISEC but don’t have one yet?  Do you want to practice so you’re ready once your OMNISEC is installed? Or are you simply looking for a way to gain more experience with the OMNISEC software?  If…READ MORE >

Scientific research is constantly expanding the scope of human knowledge at academic institutes, businesses, and elsewhere across the globe.  Malvern Panalytical is proud to play a role in this incredible work, with the goal of making sophisticated measurements and analyses…READ MORE >

The primary goal when employing gel permeation / size exclusion chromatography (GPC/SEC) is often to determine the molecular weight of a macromolecular sample.  Multi-detector systems, such as Malvern Panalytical’s OMNISEC and TDAmax systems, are able to offer a range of…READ MORE >

There are many things to consider when maintaining a GPC/SEC instrument: the mobile phase, the column set, the pump components, the post-column filter, and up to four different detectors…all in a single system! And that’s not even accounting for your…READ MORE >
