  • Process analytics in polypropylene (PP) plants – Case Study

    Polypropylene Polypropylene (PP) is a generic name for a family of semicrystalline polymers. PP, as well as polyethylene (PE), belongs to the group of polyolefins, that are derived from a group of base chemicals known as olefins. Polyolefins are made by joining together small molecules (monomers) to form long-chain molecules (polymers) with thousands of individual links using a variety ...

  • Building analytical competence for geoscience students through use of Raman spectroscopy

    Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory.
