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 >

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)…READ MORE >

When you think of Houston, your first thought might be ‘Houston, we have a problem’ – a (mis)quote from the Apollo 13 space mission.  Home to mission control for NASA space flights, Houston has been at the center of many…READ MORE >

I recently came back from a sailing holiday in the Caribbean.  I hadn’t been sailing before but I couldn’t help but think that the ropes we used make the perfect analogy for polymers. In simplest terms, the longer the rope,…READ MORE >

That’s U-tube (Ubbelohde Tube) – not YouTube! Automated Dilute Solution Viscometry (DSV) systems directly measure the relative viscosity of dilute polymer solutions, allowing the determination of intrinsic viscosity, a parameter that correlates with molecular weight, itself a defining polymer characteristic….READ MORE >
