Recently, we published a blog on Zetasizer red sensitivity. That post was specifically for the Zetasizer Red series. So how about the Blue series? What are the minimum polymer concentration requirements for the Zetasizer Blue? Therefore, let’s discuss the Zetasizer…READ MORE >

Gel Permeation / Size Exclusion Chromatography is the ideal technique for determining the molecular weight of macromolecules.  In addition to molecular weight, other molecular parameters can be calculated by taking advantage of various detector combinations, such as intrinsic viscosity (IV),…READ MORE >

Examples of Polystyrene, Polyvinylchloride and Polycarbonate measurements When Waters Corp. released the ACQUITY Advanced Polymer Chromatography (APCTM) system for polymer analysis it brought the unsurpassed resolution of UPLC separations to the polymer market. The system allows resolution between polymer fractions…READ MORE >

A couple of weeks ago I had the opportunity to present a live webinar through Chemical & Engineering News about how our latest solution for Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC), OMNISEC, can help our customers with their synthetic polymer…READ MORE >

Here is an example chromatogram of polystyrene in THF. The run conditions and some results are detailed in the table below. Wikipedia: Polystyrene is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. Polystyrene can be rigid…READ MORE >
