OMNISEC

The world’s most advanced multi-detector GPC/SEC system.

OMNISEC is a powerful tool for taking control of the performance, quality and value of your product, whether that’s a synthetic polymer in industry, a natural polymer or polysaccharide used in food or pharmaceutical products, or a protein or antibody used in biopharmaceuticals.

English version
Le colloque national du Groupe Français d’études et d’applications des Polymères (GFP) est le congrès français majeur des polymères.
La 45ème édition s’est déroulée récemment à Marseille sous l’architecture audacieuse de la Villa Méditerranée, conçue par Stefano Boeri, acteur engagé de la scène politique et culturelle italienne.

Durant ce congrès, nous avons présenté les avantages du Viscotek SEC MALS 20.
Le détecteur de diffusion de lumière multi-angle Viscotek SEC-MALS 20 peut être utilisé sur tous les systèmes de GPC/SEC et notamment sur le dernier OMNISEC de la gamme Malvern. Les signaux des 20 détecteurs du SEC-MALS …

Multi-detector SEC – 10 reasons why protein scientists need one
In a previous post I listed the top ten reasons why a polymer characterization scientist might want to upgrade to multi-detector Gel Permeation Chromatography/Size Exclusion Chromatography, but there are similar points to be made as to why a protein characterization scientist might do the same.  We often focus on the benefits of our own systems but sometimes we may miss the benefits of the basic technique.
If you are a protein characterization scientist and you find yourself thinking, “My UV detector works …

Gel Permeation Chromatography (GPC) is a very popular analytical tool for characterizing natural and synthetic polymers.  This Wednesday Dr. Wei Sen Wong will show results from Triple Detection GPC systems for various polyacrylonitrile (PAN) samples in a webinar presentation.  Molecular weight (MW) distribution and structural information (Mark-Houwink plots) are of special interest to PAN research as well as for product and process specifications (QC).  His presentation shows GPC data that differentiated PAN samples with copolymer and/or branching features.  In addition, flow injection polymer analysis (FIPA) can be a fast and reliable tool for …

When we are talking to customers about advanced Gel Permeation Chromatography (GPC) systems, we can explain why ours are the best on the market or how their excellent sensitivities means you can measure polymers with lower molecular weight than ever before.  We could tell you how the latest system, OMNISEC, reduces servicing time and costs with its new design of viscometer. Sometimes though we come across the question of why someone would want to invest in a multi-detector advanced GPC system.
Maybe you are thinking, “I’ve got a conventional system with …

I’m currently at Pittcon, the annual laboratory science conference and expo.  This year it’s in New Orleans, not too far from our factory in Houston.  Since New Orleans is known for its Cajun food and the Food Labs conference is going on at the same time, it made me think of the ways OMNISEC, our latest Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC) system can be used to support work in the food industry.
I’m sure you know that there are plenty of polysaccharides in processed foods but did you know how …

Hello everyone! This is my first blog so I think I should start by introducing myself.  My name is Amy Durrell and I am the Applications Scientist for the separation products here at Malvern Instruments.  My role is very varied as I am responsible for pre-sales sample analysis and I see all sorts of samples coming to the labs.
Recently I had the chance to be involved with the launch of our new complete multi-detection SEC system, OMNISEC.  This was my first product launch, so it is something I was very excited …
