Polyolefin – We explain Polyolefins for you

What are Polyolefin Polymers? Polyolefins are macromolecules formed by the polymerization of olefin monomer units. The IUPAC nomenclature term for polyolefins is poly(alkene). The most common polyolefins are polypropylene (PP) and polyethylene (PE). These polymers are prevalent in a wide…READ MORE >

New: Protein Columns for light scattering

Light scattering in chromatography can sometimes be challenging: The scattering signal is proportional to the size to the 6th power, and that is why particles in the mobile phase can lead to noise in the light scattering detector. Now we…READ MORE >
